/ic/ - Artwork/Critique

did this yesterday during stream, after practicing sketching faces from reference, wanted to try one face without ref. Still not happy with the resulting anatomy, especially the eyes and mouth area. But the thing that annoys me the most at the moment is that the cum looks so much rougher "sketchier" than the res. not to sure how to blend this kind of liquid to make it appear as smooth as the rest of the image.
Please note, not trying to talk about overblending (another problem of mine) just making the image appear as one
