New guy looking for feedback/critics

Alright, So a month ago I bought my self a D7100 with a few lenses and a tripod.

I've been reading a lot on the internet, but now I think it's time for me to start posting on

forums and get some feedback/critics so I can improve my work.

So here are a few of my landscape photographs I took.

This was taken before i bought my DSLR with a Coolpix. It's in the high arctic a few km of CFS Alert where I spent 7 months.

Taken in the high arctic too with the coolpix.

Taken with the D7100, 35mm 1/4sec, f/

D7100 35mm 2sec f/2.8 iso 500

18 iso 100

D7100 17mm 1/8sec f/18 iso 900

D7100 35mm 1sec f/7 iso 100

D7100 17mm 4sec f/4 iso 500

Looking forward to the comments and feedback/critics.
