I think the spruce leaves contrast poorly with the other colors in the biome, and the shade of purple for the grass is far too light, a darker, more reserved shade would probably be ideal. Maybe something like 834d9c?

Hmm, that might still be too bright...
Maybe 553a62 instead
Aside from that I like the vibe, mushrooms + Tall trees is always a nice combo for a more fantasy themed biome
Alternatively, if you wanna keep things a lighter shade, maybe make some custom trees that use something like birch or acacia, as opposed to the stark contrast of spruce wood and the dark green spruce leaves
Although, the shade of grass would still probably need a change, because it clashes with everything else as well. Its just you'd need something darker and more reserved if you wanna keep the spruce, but you can go with something paler, calmer, but still more bright if you go with a different tree type
Apologies for the paragraphs, I just tend to like to be thorough when people ask for feedback
Oh, also the sky color is a bit odd
Imo something a bit more subtle would be ideal, like...
More of a "Its almost sunset" shade, rather than "There is a forest fire nearby"
