My style for drawing: 1. Doing outlines on paper. 2. Capturing the photo of it/scan. 3. Importing to G.I.M.P 4. Re-drawing outlines; adding color, shades, what-so-ever... 5. DONE
But quite effective still! And I'm really fast. Sometimes I even get a full-colored, shaded deviation from empty paper to downloading in less than a hour!
