Is no one doing corrections any more?
Your main problem here is the lower body is way too small, and the upper body tapers down too much. A rule of thumb is that the legs(including feet) are the same length as the rest of the body, including head.
The angle was a bit too extreme as well, if he wasn't supposed to fall forward... I hope this helps.
I include a recent painting of my own for critique. It's already painted and finished, but it was made from my head, so any nitpicks are very welcome.
