[link] I'm practicing on drawing different human poses. You can use it as a reference if you want, although the anatomy is not perfect. I focused at drawing the shape of the bodies so I didn't pay attention to the hands and the feet.
The paper was abused, that's why it turned out like that. Just use it as a reference. It's not necessary to draw over it. If you just try to draw over it, it's not worth it. You will never improve like that, trust me.
your figures are distorted. the figure should be eight and a half heads tall to be in proportion. your close but they are off. i'm not trying to be a jerk if that's the tone your reading. i'm just simply trying to help you out and hoping that you'll improve. your almost there. peace
