that is a really interesting tree design.

But I agree about the way the colors don't work well altogether.

Yeah, the grass is definitely too busy, and too saturated. It sucks all the attention away from the objects, which are pretty nice(the log and the stump especially). I would either tone the grass way back color-wise or use those little grass clumps way more sparsely, or maybe some of both.

Nice, I like how you made the leafs of the tree ^^

the ground should be a bit more grayscale and lighter so the objects stand out better.

 Each individual thing looks nice but almost everything contrasts very poorly with the grass.
