Hands are hard to draw, but they’re an important part of a common subject, so you have to do it sooner or later. I’m terrible at forgetting to practise them, so here’s a quick outline from the memory.
Also very interesting is drawing the paws and feet of other mammals and birds. Count the bones and joints, and you’ll see for yourself the amazing similarities between us and them.
Also:
I dunno what it is about skulls, but for me and a lot of other artists, they’re a go-to subject for all kinds of drawing, and especially when we’re experimenting. I don’t think it’s anything special about skulls per se, but that it’s memetic in artistic circles to use skulls as a subject.
