The facial and body features are not quite customizable enough. For one thing, I have never been able to make a good anime character because of the massive wrinkles that are always present right around the mouth. All the anime I've seen made by other people have the same problem. There needs to be a way to completely smooth the face, making it completely wrinkle free. Seriously, when I tried to make Rei Ayanami from Neon Genesis: Evangelion, it turned out looking like a short, bug-eyed, ugly granny that couldn't even be given out for free! Even many real people have nowhere near that much of a wrinkle around their mouth. It really makes people look old no matter their age. I hope this matter can be fixed in time, I really want to make a lot of anime based characters but can't effectively do so until this is changed. I hope somebody agrees with me.
P.S. Also, could a bit torrent-like server system be used to reduce lag?
