ramping up the clouds helps a little, but I can't quite shake the feeling that there is nothing in the photo. Sometimes I like photos of nothing, but this nothing is too pretty. I think you have to commit, either put something in your photo or dive deeply and unapologetically into the nothingness.
A beautiful serene shot. If I were being picky, I'd suggest that you try and move the horizon off the midline - but I realise then you'd either lose the lovely clouds or the beautifully placed foreground edge.
