Ey there everybody

So, I've been working on this piece now for some hours but unforunately I'm somehow stuck at the trees and maybe the mountains.
Any advice on the trees ? It's suppost to be a wood in the distance but I can't get it to look like it consists of trees rather than a huge pixel mess. I'll add overall lighting and shadows in the end, I just need to get the woods shape right. If you got any spare ideas on the gras in the foreground or the mountains in the background - just spit it out, I'm here to listen

Keep in mind, this picture is still in a heavy work in progress and far from beeing finished.

Picture with plain woods, 48 colors

Picture with somewhat blackened woods, 69 colors
EDIT:
tested out some new kind of water and turned out good! I'm going to redo the whole water now.

EDIT2:
Worked some more on the water
