I'll give it a 7/10.

I like the sky colors and the angle. Downside is that your ground textures are a bit odd IMO. Also downside is the trees on the mountain seems to be floating. Upside is the perspective. On the far right side as the mountains go deeper in the feeling of a vast place is present. I just love that spot in your pic.
Overall it's nice but could be better.

Best part of all is the Right side of the pic IMO.
