To first focus on the positives, you have overlap going on, and that forces perspective, so at lest you got that much down :)

I don't know if there's any advice I can give on how to show foreshortening other than just practicing what the body looks like in space.
There's a lot of stuff you can take into account, I had a teacher who once had us do perspective according to what lens on a camera we'd be using (maaaaaadness I know) but generally I go with what feels right. and if I can't get it, I might take some photo reference, just of myself so I can see what shapes the muscles and fat and bones etc. etc. make at certain angles.

I can tell you that you always want to show the body as a whole and not have thing appear separated, like how you have the leg for instance. We should be able to see his thigh and hind parts and where the comes down into the knee and the rest of the leg.


I think you could do with more overlap in the torso, pushing it into space more. And showing the muscles in their correct positions according to what the body is doing. It's a little more complex, but with study you should get it just fine.

And I think that's it. I think observation could really help you out and just good ol practice. You have some good potential in there, you just have to hone it into something really great :)

Thank you very much for the advice! I'm glad it wasn't just me feeling funny about how the leg looked, or how his torso didn't look right. I will remember what you have told me and put it to good use. ^^
