Re: Fat Lizard...
The leg on the left, doesn't look like it's supporting his weight properly - it needs to be adjusted slightly. But then again, he might be resting on his tail?
Now an alternative could be he supports himself with his tail, and his legs are these dangly elements that sort of help him get around.
And yet another option could be that neither of his legs support his fat body very well - so they kind of bend and struggle to keep his weight up - so the upper body is in a constant struggle with his twig legs. To show this have both knees bend inward towards the middle, and have one slightly higher than the other.
