I'd rate it a 3 out of 10. There's a lot of incorrect proportion areas, and with the anatonomy.
I don't really like how the arms get super skinny, and the torso is to big for the legs. It also looks a bit crooked. You should try drawing on the paper that has squares on it to help get rid of the tilting. For now you should study the human body
. Just get some pictures and look at them trying to draw that and get it down then try your own.
