This is really cool!

Now, only because you ask...and keep in mind I really don't know as I can't draw worth a crap. Or animate.

Its not much, only really that I think the light through the leaves may be slightly odd, how there is shine on the underside of the leaf, at the edge of the hole. Maybe it'll do a spill out effect, or maybe it should be confined just to where the hole is? IDK, I dont know how light works and its pretty anyway. (The one I mean is the second one, closer to the edge of the tree and the sky).

I love the small thing, like the clouds moving. You may not notice it at first, but I think its cool!

The sound is pretty dang spot on, very fitting. Did you actually go outside and record that? XD

I think I see what you're saying about the light. And thank you! I definitely like making clouds lol, I use them in just about every project of mine hahahaha!

Not bad! =3
