1. Original artwork
2. Redlines. I changed the anatomy for a bit. When stretching your arm forwards, it means it has to maintain more at the height of the shoulder (where it's connected). This is simply because the arm has an limited reach, whether it might be forward or downward. When you draw the hand too low, it appears as if it's too long, which makes it unnatural, and makes the perspective turn out weird.
3. Filled in the detailes. Drew the puppet over the hand, and added some additional folds in clothing. Gave him a bit less hair on the top of his head. So much hair on the top of your head, would be pretty much impossible with that length... unless the guy has a secret afro
4. Optional, but I wanted to show you this. By adding shadows, you can make the perspective come out better
