I apologize in advance for beginning with a weird expression, but that is the cutest gynotikolobomassophilic chameleon I have ever seen.
Vision: aside of the trivial imbalance in the horizontal framing, the display of your selected color palette is remarkable. I also like how the color of your eyes in this photo differs from the other shades, as it makes you stand out even more and be counted as the core presence. I also have to admit that, at first, I did not see the chameleon in the thumbnail - which I guess means that you also did a wonderful job with the whole camouflage idea!
Originality: I haven't seen anything like this before, so in my opinion, you deserve a 5/5 on this aspect.
Technique: at a first glance, it is not very noticeable, but after observing this shot for a bit longer, I realized that you removed the background instead of taking the picture on a black one. I'm not saying that is a bad thing, at all. However, I do believe the removal could've been done in a smoother way, especially on the right side, along your facial shape.
Impact: I certainly couldn't skip this deviation when I saw it on the front page, so I suppose you get a full rating from me on this aspect too. In short: this is a highly artistic, creative and unforgettable shot!
