Excuse me whilst I lapse into my typical colloquialisms when I see something I adore:
This'd be terribly shiny, darlin'. Super shiny, ev'n. Tis hellfire-on-th'-plains sorta lovely.
- and back in normal linguistics; oh wow oh wow oh wow.
The composition, capturing that line of surf and the soft of the sand and the hard dark colour of the outcrop of the hill really allow depth to come into this picture. It makes the lines of white in the sky shine; lets the reflections on the sea glow; lets the sky come alive with - as you've put it - the warmth of the colours. I lovelovelove the split between the orange hues of the cloud to that blue the sky; it just makes the whole image come alive.
