I love Marceline and your interpretation of her is fantastic. You even included Hambo. In addition to the artistic skill, you got her attitude/ personality just right. Laid back, cool girl. comfortable with herself and looking for fun. Just don't piss her off or try to take Hambo or her ax guitar. Seriously, great job.
Thank you. I wasn't really sure how it was going to turn out, since the show has such a drastically different style from my own... But I was kinda surprise how easy it was to translate it over. I think I gotta try it with Flame Princess or Ice King next.
