Too much use of smudge tool
Like in your other piece, the smudge tool has been overused here. Unfortunately the forest looks more like a green wall than anything else.
The snow on the right part of the pic looks better than the other snow, you should have applied that style to the whole ground, I think.
All in all, you should really try to draw a pic with no or only little smudging if you draw digitally. To me, your acrylic pics look better btw.
Keep it up!
