excellent shot and very creative use of b/w where the colors were probably spectacular as well. very nice focus and detail with the background well out of focus. the composition is quite strong, imo. well done. bumping up
Since I am lacking in technical skills, I cannot give helpful comments. I am strictly a photo buff who is trying to improve, but as to telling you what is wrong or right, I am in no position to say. I am simply voting based on whether I like the picture or not. Sorry, maybe someday I will be able to give helpful advice
Having seen these lizards in color I would have to wonder why you would chose to present in black and white. Awesome composition. Maybe just me. Good luck
