The textures are pretty good. The proportions, while not ideal, actually do look like someone. Some people have these proportions, if anybody has ever been to a public place you will see people with all different proportions. Probably some people posting in this very thread have some strange body proportions

What I usually do is work from image planes as references. In this way I can assure that my proportions are right, however, if your drawing is not so good you should work with real photographs as reference.

However, believe it or not, the best help a person can get for learning proportions is hearing feedback and criticism from others.

Why are the pants rolled up? Is he going to wade in the pond?

Did I mention that I like the textures a lot? ...oh yes I did mention that

~Good luck!
