Every race needs another pass to address the lip disparity between DT and EW.

If that doesn't count as "one thing" since it's technically all of them, I'll vote for slightly stronger AO on the models. There's a lot of skin creases and borders where one part of the body occludes another that has a problem with the two surfaces blending in with eachother when there should be some shadows. (lips, eyelid creases, nostrils)
