Reminds me of art from Harry Potter GBA game, and that's a good thing since that art was done by Henk Nieborg:)

Certainly reminds me of the tree boss in Dark Souls 3. Very nice and clean artwork.

This is fantastic. Beautiful rendering and colours. I do feel there's some slight depth issues with the bigger tree, and the lack of rendering on the trunk there kinda makes it stand out like a sore thumb compared to all the other amazing detail. I'd say give the big tree a little revamp and this is pretty much flawless. 

that grass is tight

Beautifully done! Especially a part with smaller trees.

Very good.
