Depends on what you're looking for. Anime stuff, you can browse for MMD stuff from Deviant Art and some japanese sites that are listed off in the OP. These are the most modular and customizable ways of putting together an avatar, but it can be a bitch and take a while. You could also try ripping assets from games you have on your computer, and though this would be far more difficult to modify going forward, this is the easiest way to get an avatar that, likely, nobody else is using anything similar to. The easiest way to get an avatar is to buy some assets from booth and then modify it, which dozens from /vrg/ have done. You could probably ask one of those booth users to share it with you.
