Hey Joe, welcome. I'm not the expert but I'll give it a go. They all seem to be drab and lacking color (Because of the grey skys). But I wonder in post if you could bring out a little more color with saturation.
#1 and 4 are good but need to off center the building for greater effect.
#2 I like but I think could benefit from a lower angle to get some more of the water and possibly the horizon in it.
#3 doesn't really do anything for me.
