Do you draw on paper as well, or soley on a computer? I can show you some pretty neat art programs if you would like. 
I have drawn on paper before, but I prefer to draw on a (desktop) computer (with no tablets or anything of the like aside from a mouse and mousepad) because I think that makes it easier.
This, however, wasn't drawn on my computer, but on a laptop that I have (
we have a lot of computers).
