I feel like he's going to tip over... he's leaning a bit to the left. My left, not his.

I like the design, though!

Ah, yeah sorry for not giving a reason. I feel as if it is possibly to simple (mind you, simple doesn't always imply bad), maybe if you could make it look more like he's floating. What could be making me dislike the animation could also be how the stars move. Any how, I'm looking forward to your next piece.

Thank you. Out of curiosity what don't you like about the animation? This was the first animation I ever did so feedback is appreciated :)

Thanks for the feedback! I reuploaded it to the original which hopefully fixed the rescaling issues. I didn't realize scaling down would change so much, thankfully I still had the original :) 

There are multiple resizing issues. Also there are more colors than you probably planned, possibly because of the resizing.
Resizing / scaling pieces for PJ is not necessary because of the zoom feature. Don't, esp if you don't know how to do it right!
Hopefully you've kept the original version. If it's larger than 100x100, don't downsize it for the preview (downsizing pixels isn't possible), crop a significant part instead.

 I'm not a big fan of the animation to be honest by I really like the concept!
