Okay at this point I think I did all I could do. So I first saved the .psd file, then I flattened it. then, ctrl-j (copy the background) and I'm ready to apply some sharpening. for this web display, I first resized to 800x533, then I applied unsharp mask settings of 150% amount, .4 radius and 0 thresholds. do your usm this way, and you can easily see the effect by clicking on/off the eybeall in the layer... and in this case, if you did that, you'd see the window lights in the buildings just pop with a bit more brightness and clarity! Here's the final version (photo by florindo gallicchio):
