Wow, fantastic capture. If this is your 'teething time' I can't wait to see some more matured shots!
That dark spot is very distracting though. Try a proportioned crop to the beginning of the orange in the sky maybe? That should leave a more tasteful amount of black out without taking too much of the reflective water out.
No idea what I did to the blues. I adjusted the saturation a little. I used some contrast, yes. I am totally 100% new to photoshop elements, so as said, teething time for me.
