Yeah, some sweet textures and stuff. There is a lot to look at in 4 pieces of varying completion though. Fav is the last.
I'd add that in the first 'un the nose ring is forming a weird tangent with the whole outline of her left nostril, the earring also borders the cheek there too, seemingly against gravity; not a biggie but eh.
The Cowboy's cigarette terminates on the border, and the crop to the middle of his eye is strange one, I'm not sure we'd see his traps up there by his mouth unless he was seriously built, could be a bulky jacket, but what I'm saying is that you could be paying more attention to composition/framing too, looks like you might have drawn outwards from the face each time.
