Late critique is late. _{I just can't help but say something on this.}
You've done some amazeing job here. I usually start with the pixel art on critiques, but I have nothing to say about the pixel art now. Nothing else but awesome.

Well next, smooth animation is smooth. And the stuff I may want to point out are very minor.
That guy's snoreing is odd. You should've changed something on the emote's body too, something to show that he really is snoreing.
And the orange emote on the swing. The shadows on the ground are really nice. But the swing moment itself is a bit odd, I'd move the emote a bit more backwards.
Just because there;s a feeling that he comes forward, then he gets back and then he's stopping on some invisible wall or something._{My poor english can't explain everything normally.}

Overall, amazeing piece.

Alright! Once more, a fantastic emote! Just looking at it, it's awesome. But let us go deeper so see how we can make it better!

The background and sky and trees are all well pixelated (and the emotes of course).

I love the lily pads (or whatever they are called) in the pond/lake. And those low clouds in the background are quite nice too.

It'd be nice if they were reflections in the pond.

The mouth on the snoring emote closes too fast, or rather it just needs some transition just like how it is opening.

The fish are all to clustered and they are going pretty fast. They should kind of go out one after another and a little slower.

The swinging looks a little odd when it's going back, like just a little piece is going back. The whole swing should kind of all go back inwards.
