Here's a variety of the colorways for my Paleo-Dragonflies. They're all basically brown with red wings. I mixed up the brown from yellow, red and blue, so depending on how I mixed the ink, it got lighter or darker.
I like that frankly because I go mad doing the same thing over and over again (makes you wonder why I'd want to do editions, doesn't it?), and this way I can entertain my brain while I work. ;-]
