Down below are the concept drawings that went towards the creation of the sack, in addition to the character page, and the background that will be used in the final animation.
Here are concepts of how I want the sack to drop. I got bored waiting for the monster draw to begin, and I yanked out my sketchbook and jotted down some ideas, on how I want the fall to begin, plus a little thumbnail image in the far corner of the page for the path of the fall. Then including my bottle of tea that I was drinking to challenge myself.
