Hello everyone!
First of all, excuse me for making this thread since I bet these kinds of things get posted here on daily basis.

Ok, so, I am trying really hard to learn to draw human figure.
Currently I'm doing Riven Phoenix's online course called "Drawing Human Figure From Your Mind", I'm already on the lesson 76, I already know all the skeleton, all individual major bones, like skull, scapula, chest cavity etc, side, front and back view and just now I started learning all the muscles.
I bought 2 different Anatomy books, and just today a book called "Drawing On The Right Side Of The Brain". I'm practicing all the time whenever I got free time, approximately 2-3 Hours daily.
Sadly there are no drawing classes available in my area, and I find it very awkward to draw people in public, and neither do I have anyone to draw at home.

I've really progressed during the last few weeks on the anatomy, but I still have completely no Idea how to draw humans in motion/gesture drawing, or whatever it's called, for example, from a reference like this http://www.posemaniacs.com/archives/1611 ,If I try, It looks simply horrible, out of proportions, perspective is completely non existent, and , yeah, to put it simple, horrible, as if skills I've learned so far does not apply here, and it's really, really frustrating.

So the question would be, what could I possibly do to start learn to gesture draw/draw humans in motion/foreshortening?
Are there any good books out there? Online courses?

Thanks! Appreciate all suggestions!
