Nice work
I would suggest the addition of sound though, but be sure to choose something mellow and fitting, but not too elevatory, I think you did a great job of this and although, you self describe the animation as crude I would disagree, although, the drawing quality is simple, it's effective form a design standpoint, which is what's important here, and drawings aside, the animation itself has rather high quality, so don't knock yourself too much, you did a fine job of it.
