On drawing, like, tutorials? tips and tricks?

I've pretty much got* heads down (I know there's stuff I need to work on though), after all it's what I've mostly doodled... But not arms, hands, feet*, legs, body...

Don't let what I've drawn fool you, they were strokes(hah) of luck. I know how the body's supposed to look and I free-hand it to the best of my abilities. But it's really, really hard and takes a long time for me. I know it's just circles, ovals, ellipsoids, and some weird funky shapes from time to time.

I mean, I do know how to do it, but when I try and put it together my brain just flops.

So anyone got any advice? I need some help with hands, paws, feet, legs(digitigrade, unguligrade, and plantigrade, hell even birdy legs[idkthenameforthatone]), bodies, hair, and well, manipulation of those all..

I know I need to practice and such, I'm just lost @m@

Anything would be much appreciated! Anything! ~ <3
