Am I weird to say that I actually find feet fascinating to draw?
To me, feet are an exciting challenge. Whenever I draw full-body stuff I often find feet the easiest part to draw compared to the legs. Maybe it's because feet don't have that much of a focus when it comes to drawing, except that they're the very things that make your characters connect to the backgrounds.
I often have trouble drawing shoes and boots though. Maybe it's just my lack of design, but I don't know some artists draw cool looking shoes.
