Tutorial for making better computer graphics?
Not displaying them with code, actually drawing them. I'm pretty good at drawing on pencil and paper, but no matter how much I practice I can't get any better at drawing graphics for my games. All I want is to make simple graphics like Commander Keen had. Not realistic just nice looking. There are plenty of hand drawing tutorials, is there any for computer drawing? I don't really understand what makes it so different and so much harder to me.
My searches have found nothing but tutorials about programming, advanced photoshop techniques, or 3D graphics.
