I have read some books about anatomy too. The reason for both of the drawings (the one in the other thread) and my next piece as well I think (cant really remember it :S) to be not anatomically correct is because I had no intention to do so.
80% of the time when I'm drawing I start to draw a weird shape or form and see how I can go from there. I dont use any reference other than what's in my head. With the demon I started on what later became a wing and with this fella I started with the belts around his chest.
I decided that I would just focus on coloring, since this is fairly new to me. I didnt think coloring could be this much fun tough

. I'll definatly colour other drawings I may have in the future.
I still have 1 drawing which I had photographed, after I'm finished with that 1 (tomorrow or the day after) I'll start to draw some anatomically correct people
