I C. It's very nice.
I can't draw real people from mind either (but haven't drawn very much for a very long time now).
i haven't drawn anything in a long time as well. For me, it's more like, coming up with a concept, an idea that takes longer than to just sit there and draw. I can't just start sketching because people want me to, i have to have a vision of the image in my head before i put the pen/pencil/brush to canvas. but drawing here and there is just so i don't lose the skills.
