Initial impression: Great image but oh so small! Never be afraid to max out the dimensions, especially with an image like this.
Technical: DOF looks quite good, composition draws the eye to the mountain on the right. The sky and purple/blue tones help offset everything beautifully.
Artistic: Love the sage and scrubby land of the desert visible in the foreground, give an idea as to how darn far away those mountains are. Terrific pan work.
Overall: Again, just aching to see this shot, completely maxed out in terms of dimensions (or as much as possible without distortion).
Good work, keep shooting and don't be shy about going BIG!
Nice panoramic. The colours and textures and patterns of the clouds immediately catch the eye and create a sense of dynamic tension and quick movement. After studying them for awhile, then the jutting grey hills and peaks come into focus and only lastly the scrubby foreland of this vast Arizona landscape. Wide, balanced, evocative of desolation and wilderness.
