The clouds are very dramatic, and not overprocessed, to my eye. Well done!
The distortion (barrel and keystoning, I think) I find unattractive and distracting. It doesn't look accidental, at least, it's clearly a choice on the part of the artist, but it's not a choice I like much
The buildings look curiously flat. It's partly because they are backlit, but there's no real variation in tonal range building-to-building, which might just be the way Nashville is made, which is a shame. The skyline itself simply isn't that interesting. Strong compositional choice to bring it down to the waterfront and the river on the bottom, it gives a well weighted bottom to the image. There's still mot much to look at down there that's appealing to me, unfortunately.
This picture seems to be mostly about the clouds and the light, which are far and away its strongest points, and I think those are ill served by the relatively plain city underneath them. I'm not sure it's possible to shoot this sort of thing in Nashville in a way that appeals to me, but I think that if you could find more interest in the buildings, more tonal variety, and maybe get find a location where the ugly rectangular block buildings are less obvious (the ones at the right of the frame), it would appeal more to me.
