AT: Boogey Time at the Ice Castle

I managed to finish this in time for Omni Expo!  Yay!  This is my very first Adventure Time piece.  I knew I wanted to do a music poster with Marceline, but I couldn't decide whether to have her with Princess Bubblegum, Jake and Finn, or Ice King...so why not all of the above?  The hardest part was the composition, and figuring out what to do with the background.  I was between the Ice King's palace or the Nightosphere, but for this poster I liked the blue abstract color scheme better.

I hope you like it!
