These are just so so IMO, except for the last one. In particular,
#1 needs something more to make it stand out. There is not really much there to look at, objects are too far away.
#2 is too dark, and again, objects are too far away to really notice any detail.
#3 is cool, but looks like you had some camera shake because of the low light. A fast lens would help on that, or crank up the ISO a bit more to compensate.
#4 is hazy and lacking contrast. The composition is pretty good, but the top of the mountain is cut off, and the foreground is not all that interesting.
#5 definitely stands out as the best one for sure! Great composition in that one, and good color.
All of them need to be posted as larger images, at least 600 pixels wide. Its very difficult to critique detail with this size of image.
