/ic/ - Artwork/Critique

Alright so I've given up on this photo study but I thought I'd just drop it in here as is for some critique. The purpose of it was teaching myself how to render skin that looks appealing, and by personal taste I think what I've ended up with looks too oily. I was more so aiming for a "powdery" matte texture but I think part of it was a result of the brush I used. As for the colors, I was told that I should incorporate a variety of different tones so I kind of tried to but I didn't know whether to take it farther or dial it down, so I settled where I thought okay without bastardizing the photo. Thanks for your input in advance guys
