Keep working on it
A sexy picture, but there are a few unnecessary lines. One on the left of her hip connected to the panties, another that seems to dark on the right side. Her stomach seems to overlap her panties like a flap, and that red and black smudge doesnt fit with the background. But if thats your way of personalizing it then dont let me stop you. Still, the rest of her body looks great and her face is beautiful.
