It's a good thing we have a face customization tool. The different facial features are hand-modeled instead of blend shapes.
True. I could probably make my Khajiit look a hell of a lot different than the one in the screenshot if I really wanted to.
Here's a good comparison between Oblivion's and Skyrim's Khajiit. I say his legs are bent further than normal. Of course everything would be thrown out the window if the Khajiit was standing on a staircase.

Yes, his legs are definitely a bit different than the Oblivion model. I doubt it's just his combat stance. Hopefully we'll get something closer to http://digicoll.library.wisc.edu/Science/data/images/MmBib/VetAnatImg/xlarge/0054x.jpg rather than http://courses.washington.edu/chordate/453photos/skeleton_photos/cat-hind-leg.jpg or http://www.marija.savic.ca/images/still_life/images/leg%20bones.jpg.
On another note, that body fur is amazing.
