This was a tough piece for me.
Halfway through my work on this, the picture glitched (and remained glitched!) so that I could not see the layer that Marceline is on at all. I had to constantly save and watch the speed-paint, because that was the only way to guess and check where our vampire was floating!
Despite the trouble, I'm happy with how this came out. It's all about our favorite princess, scientist, defender of justice, and sweetie of Ooo!
I hope you enjoy this Adventure Time draw!
