Sorry there's not much. I would have done a more thorough tip sheet but im soooo tired, I make another one soon-ish^^
Okay drawing feet? here are a few tips
Not as hard as hands but don't really get focuses on so its hard to learn to draw them >.<
First things first, break the foot up into shapes, ( seen on the top right in red). This will help you draw the foot in the angle or position you want it.
The whole foot doesn't touch the ground, there is a portion that doesn't. This part is on the side with the big toe.
The toes are similar to fingers, the big toe and the little toe and the one next to it curve toward the inner toes slightly, while the two next to the big toe or roughly straight.
With the ankle, the bone on the outer side is higher than the bone on the inner side of the ankle (check top left drawing )
Remember you can use your own feet as references. Just look at them or use a mirror.
