I'd also add a few frames with him moving the tree back. Unlooped animations always look weird.

Smooth animation, good work!

I'm very impressed! the animation look good but i think it cuold be improve a bit but in general it's a really great work!

I added an extra frame just before it lands as it felt a little jumpy but I definitely shouldn't have. Thanks for the feedback <3

I really like the animation--very fluid and the sprite has a lot of character / style as well. Only thing I would change is remove a frame somewhere in the middle of the swing, to make the tree look like it goes faster (which would give the swing a lot more power)
