Wonderful capture. I like the subject and the pose/composition/crop. A little more mid-tone contrast would help this in my opinion. And if I were editing it, I might boost the saturation just a little. Still well done and I'm giving a good score.
Hmm, Monitor Lizard? He looks like a true-to-life dinosaur. Focus seems a little soft, but I like the lighting. I also like the blades of grass in his face -- makes the picture feel more "wild".
