Nice captures, Tlempke.
Of the two, I think I prefer the 2nd one.
I like that you've chosen monotone for it. For some reason, I think the orange clouds in the 1st picture detract from the stark personality of the structures. By going monochrome in #2, you've put the focus not on color, but on lighting and perspective.
Also, the composition of #2 places the focus much more on the subject. In #1, there are a lot of other things in the photo, especially on the right-hand side, and I think that's a bit distracting.
I like the amount of exposure you've chosen for #2 as well -- it looks just right to me!
..But, that's just my humble opinion.
Thanks for sharing.
