Hi there, I feel that your picture lacks an object/point of interest. Something that draws the viewer eyes.
I'm looking for something that won't make my eyes wonder about the photo to search what is interesting in it (some call it lazy, some call it a must have factor in a good photo ).
I think if the main object of this pic is the cloud formation, you should include less of the building.
These are just my humble opinions, thanks for sharing the pics
