On the topic of critique though, the pic is definitely creepy (the teeth are genuinely disturbing, ha), but it's hard to judge where the light source is. The shading on the legs and antennae makes it appear that the light is coming from below vivillon, while the shading on the arms, parts of the wings and the head/neck area makes it appear the light is coming from above. Also, the lack of shading on most of the body makes it look a little out of place and flat compared to the arms/legs/wings etc.
