I just made this yesterday and tried out a new method of outlining using photoshop and it's been a while since I added some shades digitally.
Anyway with all of the rumors and pairings buzzing around Marceline and Princess Bubblegum I decided to mess with it and this comic has a couple of references, one is the table flip based on the episode "What Have You Done?" where the princess flips over a table twice, however I can't help but think that it is based on a internet "Table Flip and that's why I drew her face like that to match the said meme.
Lastly due to the nature of Adventure time being a kids cartoon I changed the dialogue "FUUUUUUU" to "RAAAAAAA" at the last panel.
