To note:
Sharpness and contrast brings attention. The abyss leading out of the pic has softer edges to suggest diminishing importance.
The clouds are in the background, and the background is not something the eye should confuse with the foreground. Some blur and/or lowered contrast might be in order at some of the cloud edges, maybe more than I did. At least at the lower levels where "Where can I stand?" confusion might arise. There are no clouds that low though.
The tree has been fogged back a bit. Note that the fog is more intense where the tree meets the ground (well, a bit, and the contrast is lower). A common trick in art is to blur and fog intersecting parts to avoid intersection confusion. This whole blur-contrast thing can be taken further than I did in my Paintover.
The ground has two hues making it more interesting, rock and dirt.
There's now an overall theme with the swirls.
Flowers can make the environment feel more alive. Maybe there's little bee sprites buzzing around them, bringing the environment to life further?
Yes, I didn't pixelate, but the same rules apply to all art, imo. Execution is just... a technicality.
