Whiteclaws, haha, I am a terrible drawer... My graphics are ridiculously simple, with a bit of fake shading added. The way I see it, the thing that makes it look nice is that there is a lot of graphical continuity, which is so important in a game.
If you draw well but struggle to get it into a computer, I'd suggest (Keeping in mind I know next-to-nothing about the subject) to get a graphics tablet or even scan it - if you do it right, that hand-drawn look can be amazing.
