The colors are gorgeous, but there's a glaring flaw in my opinion, a flaw which Alain Briot has addressed in his crop.
That small, bright, blown section of sky in the top left corner, draws the eye for no good reason. It draws the eye off the page, which is not good.
An alternative approach to Alain's, might be to replace that small section of sky with deep blue. That would add to the over all effect of a colorful image.
