I like what you've done here. The colors fit well. The only thing I would critique is the sky. It seems to be a bit detached from the mountains. Other than that, great job.
Ouch! All those pointed mountain tops - Abit scary. But love the blue and gray shades-and the shadows over the mts. add alot. It has a lonely feel to it-probably because no-one could climb them! I like this...
