Very nice,
the top is a god muted black, perhaps rub the edge of a lead pencil to sides of the magazine, I imagine these received a bit of wear, and would add both a touch of life and some contrast to the piece.
Maybe photographs against a not so dark background (a mid blue or a grey) as I think the camera is flattening a lot of subtle details on your painting....
I like the face, no make up makes sense, touch of gloss to the eyes, perhaps?
Good work overall, cheers
Jamie
