I'm not quite sure what your point was here, unless you simply wanted to entertain people with an amusing illustration. Though I love how you had enough forethought to actually show the chameleons changing color where they touch the food. The background leaves a little to be desired, and I think you could have made it a cooler color, maybe a soft purple, to make the chameleons pop off the paper even more and to bring the foreground forward. A kitchen-type setting in the background would have been cute, with a stove top or maybe just some tiles or wallpaper design.
It also would have been interesting if the top chameleon wasn't a perfect side view, and you could see both his eyes. Chameleons' eyes don't face the same direction, and I think that displaying that would have added a more interesting element. All in all though, another amazing piece from you that I find really entertaining.
