Sad Demon

Update

I know that dithering on the sky isn't so good, but anyway it's the best I can do.

Atmospheric Perspective will give you more depth by modifying the max and min distance perceived.
It will also help control focus in the composition:


Scientifically atmospheric perspective is caused by "air particles" compounding over distance.
Greater distances cause them to appear increasingly opaque:


Artistically atmospheric perspective is a collection of perspective cues working simultaneously:
1. Change in size
2. Overlap
3. Hue shift
4. Loss of detail
5. Compression of color range

This is typically simplified to:
Greater distance = Color shift to Skybox color

It's up to you which cues you want to include and how exaggerated you want them to be.

In general:
More exaggerated = Greater distance

Upon closer inspection you have a tiny bit:


But it does very little to separate the figure from the environment as can be seen by a greyscale:

I would say that the sky's colors don't contrast each other enough, maybe if you changed one of them, it would look nicer. I can see that you did the dithering well, but it's hard to see.

Oh sorry to necropost guys, I want to finish that.
PixelPiledriver: Well, it's true that my scene hasn't got so much athmosferic perspective but if i change that I'll have a palette problem and I don't want an overfoged sense or so much focus on the monster because the demon is important but in that case the backgound is important too.

I tried to make a fire effect on the sky.
