Everything's alittle derpy, since it's just a sketch...it's based off of Mami's Death scene from Puella Magi Madoka Magica. It says 'Mami's Demise' in the corner. Some parts of things are erased because I edited it a lot, so...yeah. Total time was about 5 hours ( three in school, two at home) and a couple resources were used to edit it.
