Your welcome. Ah thats what I use as well, I like using simple things, that way I can draw at my best anywhere! And 10 hours? Ok I don't feel quite as bad about myself now lol My average drawing takes 1 1\2 to 2 hours.
I myself am quite lazy, which is why I'm surprised that I sometimes hurry my drawings, I think it's a desire to seethe end product, but I'm working on that. And I hate to correct you but I think all time has been going on for more then 10 hours... or did you mean thats the sum of time it took you to make this?
