The faces are a bit weird... but all the other things look pretty much right to me.
But then I don't really know about doing things right, so my opinion probably isn't worth anything one way or another. =/ ... Sometimes I feel like everything in the face ends up focused not so much on the eyes as on the nose. Like how one draws noses really sets the tone for the rest of the character. I pretty much always get weirded out if I try to actually draw the tip of a nose... so I always stick with just the line-for-a-shadow-underneath approach... but because that is me I always end up doing it wrong or putting it in the wrong place and screwing up anyway.
This isn't about me though. This is about you.
And you're probably groovy. I don't really know you though.
