Today Amber-Aria had a sketch stream, and this is what I got! It's an odd little idea I had a while back, and it came out wonderful. She can change color like an actual octopus, too! Usually she's blue with black and neon-blue stripes, but she obviously felt pink today.
The art is copyright to Amber-Aria, and the Octogirl is copyright to me. :)
Addendum: Some neat stuff on octopi! Notably, my character doesn't have all these features, notably her blood is red, not blue. http://animals.howstuffworks.com/marine-life/octopus1.htm
