i recommend using a reference for bodies, your neck is way too big for the body, and the fingers on your hand change shape as the character waves. the thumb also looks like the other fingers instead of being lower, making it look a bit off (unless it was intended to look that way). don't take this the wrong way, i'm not trying to insult you, i'm trying to help you improve. i drew kinda like this when i was 11, don't worry.
