Same question with this one as I had in the last one. Was this taken with a camera or a scanner? I think a scanner would have gotten rid of the slight blur that was created. If it was a scanner then... bad scanner bad...
It's bent leg seems that it will be way too short when it's fully extended... so I measured... and I was wrong. In fact, the foot will make it an entire lizard foot longer than the other legs. Maybe that's too much attention to a cartoon style though.
I really like the shading with the green. I'm not sure if it just naturally happened because of what you were using to color it or if you did some of it on purpose. Either way it's very subtle, but adds some nice texture to him. The mouth bothers me ever so slightly because of the white emptiness that is the outer part towards the bottom left of the screen. You did a good job starting with black in the inner most reaching, but it would have been nice to see a gradual shading all of the way to the end.
Another cool cartoony/tattoo type of drawing. It was a little empty because of the pure white background and would have been a little nicer if there was some more added to it. I can see him on a different shade of green grass or jumping/hanging from a small branch/twig or something.
