The stock in the front looks really LQ, and the blending from the snowy mountain to everything else is kinda bad if you look at it, but other than that it's really cool. At first I was thinking, "what did you do to it?".
You can definitely tell. Look at the lighting variations between the mountains. Not the big one, but the small grassy ones.
Now fix that sudden line that divides the grass and the line. The rock should go into the grass like tree roots do.
Lol, it says 'NTART' in the bottom right? I assume it said 'Deviantart' and you forgot to erase it all... And get rid of that annoying smudge in the sky.
