It's a bit backward from the way most people do it - they make sketches and outlines, then add color. But I find that this works for me, especially because I tend to make some body parts too big on the first pass, and having a color blob lets me use the eraser to chisel it down until it's the right size.
I guess my drawing style is more like sculpting than sketching, haha.
Did you enjoy this quick demo, and would you like me to share more detailed behind-the-scenes information about my drawing process?
Let me know in the comments!
