I think a selective desat to leave the red of the woman's dress and the red/orange of the wood chairs would be a very interesting feel to this. But selective desat isn't everyone's thing.

something you seem to have a wonderful talent for is light .. shadows .. and just getting it right .. this is brilliant .. the sun and the shadows and the table and chairs .. what a great find .. :)
