The house looks extremely natural :o! How you did it?
Well, sea looks more like distant hills, I think it would be better if horizon would be absolutely horisontal instead of this blurry case of sea you're having right now. Actually, these screaming contrasts remind me an old game, "Shadow of the comet". Experiment with less contrasty colors on seawater, I hope this helps. Apart from this, everything looks absolutely ok and beautiful.
