Very fine work, dude.

If I may provide one minor criticism (and feel free to ignore me), after watching the gif, my one critique would be that I think you went juuuust a smidge too dark with that final shading on the left side of her face and shoulder. It looks like a more direct shadow after that final pass, but doesn’t feel consistent with the shading on her chest or the placement and intensity of the highlights then, which seem to be much softer ambient lighting. And I think it lost you a bit of definition and detail on her face and eye. In my opinion, it looked most natural and defined, I think, right at the 57 second mark in your gif before you darkened the irises.
