Let's ignore the head, yes? Okay, fine. You can talk about it, but be nice. I already know it's a problem and have some ideas on fixing it. Feel free to give me any advice you might have, but realize that if it's on the To Do list, I'm gonna get to it eventually.
Fix that head. Ugh.
Tail and legs are too skinny. Give that kid some meat! [Check]
Speaking of the legs, where'd that last joint go? [Check]
Okay... Pretty much everything is too skinny. Widen the main body portion. [Check]
Add fingers and curve them a bit.
Fix the puffs of fur around thighs. [Check]
Make the arms a little better?
Make the main body less blocky?
Um... Make one, not just that test thing you've got there.
