A lot of the prebuilds can be made to look great without much effort. For a couple of races I know which preset to use and how to change it to make it looking to my liking. A lot of the ugliness comes from the complexion and dirt sliders. Oh and for the Wood Elves, you can always change their eye shape so its less slanted vertically to a normal horizontal direction with a slight slant. That's what I prefer on my Wood Elves. Just sit around in the creator for a little while and figure out what you like. My strategy is I don't mess with the face sliders much because when you figit with them and you don't know what you're doing (me) it can get pretty ugly. So a recap. Complexion and dirt sliders are a general cause of ugliness. Eye shape is also important. Keep it simpler for better looks in my opinion. Provided you're like me and just doesn't like to mess with many of the face sliders. The biggest tip I can give is to find the best looking (in your opinion) face on a preset, then work from there.
I don't normally rate dudes, but when I do, they are usually elven.
Anyway, I agree with this poster. I'm on 360, so I can't post but I remember creating my woodelf. Try the preset under the second "e" in preset, it is #6 on 360. Then drop his complexion all the way to the left. Adjust skin tone/hair color as necessary.
