I delightfully love this image, the only criticism that I can derive is that now that its been shown what Marceline's nose looks like (being slit nostrils, though not like his highness snake face a.k.a. voldemort), the nose is wrong. but thats pretty much it.
Oh lordy this is so awesome, I was so giddy when I saw this for the first time. Did you know a lot of YouTubers use this picture as a thumbnail for some fan-put-together Adventure Time OST? That's where I saw it, and I figured it might track back here.
GREAT SLAM-DANCING HUNGARIANS VOICING THEIR RAGE AT THE APOCALYPSE WHICH COMES FROM ALL THINGS DISDAINFUL OF TABLE COVERS, THIS IS AWESOME.
Seriously, this is just about the BEST fan art done for 'What Was Missing'. I REALLY like Finn's hat. That is an awesome hat. I WANT THAT HAT. You have inspired hat envy in me, sir, and that is glorious.
