I'm not entirely sure you're looking for criticism based on the plug, but here goes.
This is, overall, not a bad piece of digital art. The character design is cute (love the "lick here" tattoo) and it seems just right for the intended audience. The shoulders ruin it for me, though. Actually, the whole chest area is pretty awful. It just doesn't make any sense. I'm also not a huge fan of the burn shading for the skin, but the rest of the coloring (especially the hair, facial features, and accessories) is top notch.
