I like it. Don't think the leaves are distracting as the lizard's face and features are so interesting and they 'shout' so loudly, that I dont really 'see' the leaves.
Can't really improve much with processing.
The only improvement is the next time you shoot, to compose it better in real time, on-the-fly, and fire off 10 shots in less than 10s. ;p
OK, what I am saying is you need more experience. See more, shoot more, self-critic more, and next time you can compose, shoot and think instinctively and instantaneously.
Some compostional ideas:
1. get both eyes, or at least more of the second eye.
2. get into greater details on one eye (I can see a hint of red, and it looks exciting, and I want to see more.)
3. incl both fore limbs
Or yet something else.
You see we were not there. But you were and you must capture what is most interesting and exciting to you and to present it to us as a photograph so that we share your same excitement and delight too.
