It's good. There are some minor problems. The dividing line between light and shade is stuck a bit, and the transition is unnatural and needs to be deepened. Some surfaces should be convex. When you squint, you can see that the boundary line on the right is not turned over, and the edge line on the left can be looser, closer to reality and far from imagination. This is just personal advice. . I hope your painting will improve. Draw a small apple, and then draw something more complicated. The connotation lies in this apple.
