Allright, shamed into finishing this.
I found I really did not care for the mess of pilings on the boy's right, so I cloned those out.
I also thought the pic would be stronger if the hill in the background cut across more of the pic. So on a separate layer I selected it and stretched it across the photo, then masked the boy, pilings etc. where they crossed.
Using layer masks, I did separate levels and curves adjustments for the foreground and sky, lightening the foreground, and trying to get a bit more contrast into the sky.
I then dodged the boy's skin a bit.
Then smart sharpening, masked some in the background.
Oh yeah, I added a bit of a vignette.
