1. Sketch an awesome or lackluster--c'mon, choose wisely-- idea to draw.
2. Sketch that bad boy, or girl. Don't be sexist.
3. Scan or snap a GOOD QUALITY image. You won't have to struggle to see the reference image so crying isn't necessary. Save your tears for onions.
4. Trace like no tomorrow! I prefer a drawing tablet, but I've seen miracles made with a track/touch pad or a good ol' mouse. Hah...not for me.
