thanks for the helpfull critique always XD

Failure? No way! But it could be improved.

The 'jumps' could be higher, and it seems the second one is shorter than the other 2.

These jumps are a stress to the poor alien's body: show this. At least, his head might come down a bit at each jump, and go up during the fall. Just like in an elevator!

And, if you're ambitious, give him a changing look, maybe during the fall?
