I really don't think it's that bad
You need a bit of work, I can tell you that much. but overall it's alright.
As for critique I really can't pinpoint it that well. I have a feeling its on the arms and legs though. Don't quote me on it, but I feel as though the arms are slightly shorter than they should be, and the legs aren't the right perspective.
Perhaps overall whats off is the limb's perspective.
