Your coloring style is amazing! I love the soft yet vibrant hues and the expression on her face says she could kick your ass. I think you have the flow of her shirt to the T and it's a subtle sensuality which is a plus.
I would work a little on the foreshortening but you're not off far by any means! Mainly her right elbow/arm should be a bit thicker since it's closer to us. But having the ball in front helps with the depth.
All in all, you have great work Don't be down on yourself!
