It would be nice to see something in the foreground to give your shots more depth. On that note, I find #1 the most pleasing because it has a bit more depth.
Your mountains don't seem to be the focal point... They have almost no detail. I would try to get more detail out of the mountains and less out of the sky. BTW, That side of MT is awesome.
yes, that half/half composition does not help the shots .. in particular as you cut building in half and such.
I'm gonna have to try editing some of the sky out when I get a little time. I had to crop alot of obstacles out of the foreground on these and I think it made them kinda top-heavy.
