I adore how this turned out! Your icons seem to be getting better and better, and this one is particularly strong proof of that, imo. The facial anatomy is a nice blend of stylized realism and caricature, and personally, I like that you've toned down the square brush marks a bit to make them more subtle.

But yes.. I definitely like this picture quite a bit, and after seeing it on FA and then here, just had to comment :3

oooh this one is gorgeous!
