If you number your images you make it easier for people to c&c and try to keep the image count down to 2-3 images, that way you will get more in-depth c&c as opposed to a "nice image".
1. Lovely view, a little too much saturation for my taste. I also feel that the image is somewhat flat since you haven't included any foreground subject to give that sense of scale, and placing the horizontal line in the middle is not a good choice since the ground/sky now compete for the interest, instead of leading the viewers eye to the most prominent parts of the image. (In this image I'd suggest you crop away 50% of the sky since the fjord contain the most visual interest.)
2. Great black/white conversion and a great sense of scale! You could however have placed the silhouette more according to the rule of thirds in this image instead of centering it.
3. Nice view of the landscape and good colors, not sure if I like the underexposed parts of the bottom of the image.
4. I understand the intent of giving the viewer an understanding of the height (and some vertigo

) but, the image feels way to busy with no clear subject to rest your eyes on and with the over-saturated colors the tilted horizon and the hdr-ish look i feel the image is an abstract rather than a landscape.
5. I really like this one! Great use of the fish-eye also great colors in the fore/middleground though there seems to be a bluish color-cast and some overexposed sky on the background, still a neat capture.
6. I'd say this is the best of the bunch great colors, consider cloning out the group of people behind the main silhouette so she'll then look like a solitary.
