You just proved, it doesn't have to be complex for it to be unique. never seen one like this, and to be truthful I couldn't help laugh out loud. Your lines are smooth and you bouncy ball is unique in color. The shadow disturbs me though. It helps give the ball depth. But it also takes it away from the picture. I don't if you intended this, but its really satisfying. This reminds me of this one animation called the animator vs. the animation, only this being the Artist vs. the drawing. That would be a cool idea. I think this goes beyond without saying.
Bunny immigration!! lol I love that gif, thanks for using it so I could see and learn of it. Anyways, I love this! It's really creative and funny how you use something so simple as a rubber bouncy ball and then transform it into a huge deadly boulder chasing after people. It also reminds me of Indiana Jones haha
