Title says it all
Thought it could be nice to see what people here like most of what we've seen so far, and why they like it.
Here's me:

Beautiful. Stunning. Such great lighting and contrast. Slight blue fog, an orange/grey sky, and bright yellow fall trees, as well as a lonely pine tree. I also love the detail of the landscape in this image.

2. http://bulk2.destructoid.com/ul/199017-/Riverwood01-noscale.jpg
Really like the lighting in this image. Looks like a bright sunny day in a nice peaceful village (Riverwood). I like how the blue mountain in the background contrast to the bright sun shining on the thatched roofs. The screenshot also gives you a great atmospheric feeling of a very alive village.

This screenshot was recently posted on TESNexus in... super HD! This is the first picture we get of a sunrise (I believe). I love the vast mountain range. The snow on the mountains also look great, as well as the clouds. The image doesn't look photorealistic good though imo. But nonetheless, it still looks great!

What are your favourites?

Those are going to be awesome (in a freakingly scary way)

Also, the icy rocks look so great in the background. Looks really nice

I love them all because they are all great, and I can't choose a certain one as my favorite.

^ TES has long needed this kind of vast open plain.

Wowowow that third image on the OP is ingame? 1st time i see a Skyrim image where my jaw drops , if it is ingame OMG :rock:
That is my favorite image right now ty a lot for to share it

The badass Orc with a fro-hawk who is blind in one eye.

Chuck Norris approves!

The one I took for my avatar :biggrin: Just look how bad ass this orc is!

This one looks amazing, I mean man, that skin ... http://videogametalk.com/blog/wp-content/uploads/2011/04/Skyrim-DraugrHero.jpg

The Khajiit one.

Mainly because the khajiit look absolutely badass in Skyrim, instead of the doughy cat they were in oblivion, they actually look ferocious. Awesome stuff.

I really love http://console-gamers.net/wp-content/uploads/2011/04/skyrim-4.jpg. It's so beautiful and peaceful. I can't wait to find this location when the game comes out. This is also my desktop wallpaper. :rock:

The one with the Khajjit, it's my favourite so far.

It's so epic.

Really like that ones as well. I especially like the water. Looks really good.

Another image I like is the giant one:

Giant looks so sad

I think this one is pretty epic too. Even though it is just concept art, it is still one of my favorites.

Fallen tree looks amazing, mountain, fort, trees, what looks like a frozen pond. Just awesome looking.

I like this one because you can really see how they improved the graphics. http://www.google.com/imgres?imgurl=http://www.whyilovevermont.com/wp-content/uploads/2009/10/laser-cat1.jpg&imgrefurl=http://www.thingsithinkarecool.com/whimsy/laser-cats&usg=__QPlGz47zMBfvlfb7jm6a2o70SZI=&h=401&w=400&sz=202&hl=en&start=14&zoom=1&tbnid=WbNDF4iap0c0eM:&tbnh=124&tbnw=124&ei=QLCwTc3eJc3PiALg1ISwBg&prev=/search%3Fq%3Dlaser%2Bcats%26um%3D1%26hl%3Den%26sa%3DN%26biw%3D1920%26bih%3D979%26tbm%3Disch&um=1&itbs=1

Why? This screenshot really has a lot going for it. The first thing that'll catch your attention, is probably the Chracter himself, in what may easily be my favorite armor set of any TES title to date, I could go on for a good page or two, as to why I find that armor (minus the helmet really) so appealing. But suffice it to say, it is an amazing blend of abstract, and elegant practicality that I found enthralling to look at, particularly with the shoulder assembly, and studded skirting.

Next we have the sword. Again, it has an amazingly elegant, but practical look. Foreign, yet familiar. Nothing overtly obtuse, as we saw in the Elven sword from Oblivion.

The next big ticket, is what were identified now as, Ice Wraiths. A far cry from the wraiths in Oblivion, which were barely a step up, and in some ways (Particularly audio) a major step down from the Ancestor ghosts of Morrowind. I hope this highlights an overall, more inspired creature design for the rest of the game.

Next, is the sky itself. The overcast looks simply gorgeous. It's not really the best weather effect I've ever seen in a game, but an incredible step up, particularly as you take note of how the light is on the horizon, and the color fades as you get away from it. Instead of the uniform gray we've seen before. I can't wait to see rain, especially after the step down from Morrowind... Seriously, rain that follows you? c'mon.

Finally, we have the log, where we might be able to see, through some slight imperfection, the dynamic snow in action. Taking note of the edge, at the far left, it appears you can see where the "log" ends, and the Dynamic snow pile begins. It appears all a little too uniform, but I can anolyze Cry engine screenshots and fine imperfections too, let's not dwell on something I've obviously spent too much time looking at.

Concerns from this screenshot: At far right, middle, it appears to get a little too angular for my taste. It could just be the screenshot itself, but I was always bugged by things like, perfect angles and pyramid shapes in the zone geometry in Fallout: New Vegas most recently. On a scale of importance, with 100 being "Deal Breaker" and 1 being "didn't even notice" it's around a 0.000000000013. Still, Take the good with the bad.

The http://cms.elderscrolls.com/sites/default/files/tes/screenshots/WolvesHealMace_wLegal.jpg one is undoubtedly my favorite. Unlike many of the other screenshots, this one gives a nice overall approximation of what enemies, magic effects, and weapons will look like in Skyrim. You get a good vibe of what the overall color scheme and "feel" of the game will be like, and thank goodness it's in first person. I've seen enough of Mr. Horned Gladiator Man™'s backside.

Most notably, this screenshot has some very nice clover foliage near the bottom of the screen. Most of the other screenshots just have Oblivion-esque grass, but here the entire scene seems to light far more nicely.

Me likes teh one where... uh... I CAN'T DECIDE! I Love them all! what i think is awesome when i look at these screens and think : Oh i pre-ordered this so i will have this game.... Awesome feeling.

There's even a variety of trees in it!!!

Edit: while there's the usual evergreens there are also some leafless trees, which give me hope that the leaves are seasonal.
Seasons affecting the world would be amazzzzzzzzzzing
Plus the fallen tree, which is awesome to look at.
