I'm not sure if this goes here.. but I guess it's worth a try ^__^

Well anyway I have a huuuugeee issue.. (in my oppinion at least..) I think I'm pretty okay at anatamy, however I really really suck at drawing from different perspectives. (and i'm not sure if i'm using the correct terminology but what I mean is like drawing something like a person with his hand coming twards us.)
I'm not really sure how to do this, I can do it pretty well if I use a model (like a mirror) But I can NEVER do it with my own mind.

So I guess my question is how to learn this,
how to practice,
and anything else that could help improve this kind of thing.

Thankies >_<
