I’m glad to see you guys doing something with this. I tend to forget that not everyone has access to a copy machine, but if you can scan your black and white drawing once you have it perfect the way you want it, you can print it out on your printer.
Then you can apply color only to the print and scan that when you’re done. If you screw up with the color you can print another black and white drawing and start over.
When you get comfortable with this technique, you should try and be more daring. Take some risks with the printed copy that you wouldn’t otherwise take with an original drawing.
When I get the chance, I’ll do some master copies. For now I have to get some freelance work done.
