It seems out of focus to me - I can't really make out the lizard. The red flower on the right also distracts me because it stands out of the background. I would have cropped the right more.
This is a good photo compositionally, that unfortunately is lacking in the focus department. If you're not working with an SLR, it's likely that your camera is center-focused. My recommendation would be to center your entire camera on so at least the head of the lizard so that is in focus, then crop your photograph to keep the same proportions you have now.
Woah! Almost didn't see him there, nice camouflage little lizard. And what an angry looking lizard he is, LOL! It's funny how their eyes work, one looks like it's looking directly at you while the other is looking off to the right. :) I love that about lizards. Well, first, you get an extra point for using an animal, an unusual one at that. I like the focus on the lizard and the use of DOF, the lighting is also well done, though there is a bit of a glare on his back area. The plant on the right doesn't do much for me, could have cropped that in a just a bit for my taste. An 8 (remember you got an extra point for the lizard! :) Go feed him!)
