Help me with a drawing please?

-I really need help with a drawing that I just can't seem to finish. :c It's a guy sitting cross legged and it's a difficult position to interpret... I don't even have a mirror to sit in front of to help me, even if I could do that, it might not even help. D| To top it off, I can't even put it away to finish later(til I get better at drawing), it needs to be done for tomorrow night. ;_;

So here's the link to it: http://www.freeimagehosting.net/uploads/鈥?/a>

Drawing over it and sending it back would be super nice... :3

It's his left leg(knee)... I just... I caaan't, I dunno how to draw it! D': -sniffles-http://www.worldofstock.com/slides/PED2177.jpg this image is of a real person sitting in exact same postition, copy it. :)
Proportions need a lot of work. Needs shading. Looks bland.
