Ooh, not bad! I especially like that shading style you use. ^^
However, I think just about all these guys are, uh, a tad disproportionate. At the very least I can tell their heads seem a little big on their bodies, but in a few cases (namely Caiella's) it looks like the arms are kinda long, too.
Your faces have some really nice details going, though, so definitely keep that up! Can't wait to see who else you draw
