This is my own personal torture exercise I go through to understand directions. I have no sense of direction. You pick this bone up and turn it over and I cannot tell what direction is where now. I have directional dyslexia. It is a hard obstacle to overcome when you are learning anatomy. Cuzz I'm nuts.

Yes. I drew it perfectly, from memory.
Do you believe me? ;)

Nope. There is so much that you DO know from memory, I know you won't mind if I say that. But I know what it takes to have that skill. I do NOT have it. Artists that can draw something from memory are GIFTED. Many of us couldn't draw a straight line if you paid us. (I can, actually, it isn't hard for me) But drawing from memory? I know many that can? I am in total wonderment of them. Frank Frazetta had that kind of skill. He could paint something perfectly as if it were photographed after just seeing the scene for a moment.
I am not so lucky. That doesn't mean I don't have talent. I just don't have that talent. My talent lies in thinking out of the box and making something over and over until it is ingrained in my memory. So, I am working on the hip from every angle starting from these examples. They won't be that perfect, but they will be credible.
