The first thing I did immediately before anything else was to decrease some of the contrast + color saturation. My goal was to remove some of those "in your face" tones without losing the intensity of the sunset. I also played around with the "lens correction" feature to correct the minor slant in some of the buildings, increased the sharpness a tad and modified the orange & blue hues. I suppose my biggest problem when using LR4 is that I spend waaaayy too much time on each individual image which keeps me from having any kind of practical workflow. I'm fairly new to LR4 still (3 months maybe) so I welcome any kind of criticism. I'm mostly just eager to learn from everyone.
