Check Avatar Museums, pick one of the samples and run around in it for a while.

Sometimes you'll regret simple things like height of a model when interacting with others.

Most of those models will either have moonrunes for the name so you can search it on booth or a working link to the booth store for it. Sometimes names are in romanji and can just easily be typed in.

Wouldn't recommend starting with MMD unless you want to devote time to Blender for optimization just so people don't block your avatar
