Any crits? I'm debating on whether or not to remove the clouds, they seem out off place to me. Any help with the ship design would be nice too! I suck with that sort of thing ;p Oh and this will have parallax scrolling if I ever end up making a game out of it.

Edit: Started adding windows, not sure if should continue because it kinda kills the minimalist style I was shooting for, your thoughts?

I think I'm done with this, just uploading to see if there's any crits.

Don't know if I should have posted this in my other thread, but oh well it's picture of a sunrise looking over some water. I like how my water turned out, unlike the other, although there's probably still improvements to be made. The tree and the bush doesn't stand out as much and blends to much...

Not sure if this is a stupid idea, but I'm trying to do a landscape with only four colors so I can force myself to make better use of my palettes (I'm not great at this). So is four colors to little? Bah I dunno, help is appreciated.

Okay, so recently we started doing landscapes in my art class, and considering I've never done one in pixel art (or in any other form ) I thought it would be a fun challenge.
After about a hour, this is what I came up with. I'm aware that the left side of the mountains are atrocious right now, but I think I'm starting to get a hand of them. Anyway, critiquing is appreciated.

Edit: Tried doing grass, failed. Any tips?  
Also I haven't changed the palette because there's no quick way to do it on paint I'll get around to it eventually I've just been doing most of this at school in my spare time.
