I agree on the manes, I'd like to see fuller, broader manes (specially from the front, the ones that we have now seem to "fit"). :) The fluffy one is neat, but being textureless is kind of a turn off. x)
I could never make something that good, I'm not trying to put the designers down at all D: I know how hard meshing and texturing can be. I just would like to see a fuller version of the mane that's already available, since I like the one on the game already. C:
