A lot has been happening here, so I haven't had much time. But I did these and thought I would show them.
This one is the same line drawing as the previous post. I just scanned the line drawing before I painted it. Then colored the scanned line drawing with Photoshop.
This sketch was originally just going to be a gas mask, I got carried away.
I used the easiest coloring scheme I could think of to color it. All shades of olive green.
It's weird, though, because I am basically a pacifist. Sometimes your mind takes you to strange places!
