First of anything, a completely update of face graphics for the old races. Vieras came with a perfect skin yet the highlanders faces are the perfect example of why they need to be update.
Second one, eyebrowns for highlanders.
Then... I'd like to see body options, presets at least.
I think this game needs more long hair for females and masculine haircuts for males.
About options for the faces, it could be nice if we can just mix the options that we already have. If not, I would like to see new and more faces for each race.

Aside of "Character looks"... I'd love to see an option for the way our character run/walk. Like calm/hard. I don't know how to express this in english, sorry.
