i quite like the second and fourth. the first one is interesting but seems a little surreal. the third one seems to be a bit much like a painting, and the ground is quite distracting. otherwise they're cool
I love the first one. If you don't have anything anything editing, you could take out the building on the right side, for more uniformity/focus on the main building. It's very cool as it is though, looks like some evil fortress of something
The lights in the fog of the first one really do it for me, and if this is considered surreal then I like the surreal effect!
I also like the third with its three "layers" of things to look at, the middle one being the skyline ... and I would think it is a field covered in snow (or a parking area or something very flat and covered in snow?) in the foreground ... and I like the colour gradients in the sky!
