I wonder if you could apply a mask such that you're working only on the sky, then select the narrow range of blue-green in the pic using the sliders in the Hue-Saturation dialog box and play around with the hue and the saturation.
Another approach might be to use the same mask as above > switch to LAB color mode > go to channels > select channel "a" and blur slightly > repeat for channel b.
I don't have photoshop on my work computer so I can't try these before I shoot my mouth off but I'll try and do something this evening. Could you post a link to the original of #2?
Regarding #1: There's a bit of flare from the sun in the bottom-left part and it's obscuring the boat and some details in the house. It's not too severe but the presence of the sun draws my frame to the left-side of the pic and then the flare at the bottom distracts a bit.
BTW: What blend modes did you use?
