I can tell you my 2cents but take it with a grain of salt. The problem that I find with panorama landscapes is they generally turn out exactly as you would imagine them. If you told me to imagine a mountain landscape, this photo is almost exactly what I would imagine. The second problem is the image is soooo large that it is hard to get a 'pop' or 'wow factor'. This makes the image again, as expected. All of that being said, I think that the composition and colors in the photo are good, I just find it kinda of 'landscape typical'; just as I would with 95% of panoramic landscapes. I don't mean to sound harsh, but I think that a lot of people avoid commenting on photos that are great photos, but lack a 'wow' moment.
