[WIP]Two Heads

[Phones]

I rarely ever make larger pixel art, so as a result, the quality suffers. However, I'm somewhat happy with how this new project is turning out, but I do feel that I could use some guidance on it.

To the right is the pallete I used. Any critique on it, or should I consider it finished?

Thanks

It looks very good to me, but we can't really decide if it's finished without knowing what it's for.

It's for nothing more than practicing my pixel art skills.

It looks very good to me, but I can't figure out what the dark thing is that the heads appears from. Is it a rat or a volcano?

I find the clouds (or are they peaks of mountains?) in the distance really distracting. I'd even daresay take them out completely or make them smaller and futher apart (less is more sometimes...) as they take out the focus on the heads. I think they make the top half of the piece too busy for the overall composition.

Also the...thing connecting the heads to the dark...thing xD; Is it supposed to be smooth? It reminds me of a wisp of smoke but it isn't smooth enough to be a wisp.

Nice trippy piece though. Reminds me of Catsoup for some reason ♥

Thanks for the tips! Here's an update with a bit of a pallet change as well.

It is supposed to be a rat by the way. I'd also like to see if it's possible to get a little more color variation in here.
