Deep blue! The abysses of the sea have always been images that come back to me, although I have never dived or know how to do it; something that is in my unconscious and I don't know its origin (perhaps because I live near the sea and experience it). When I saw a film by Luc Besson that they called like that, those images were recorded for me more.
You get a good effect on your photo with that really dreamy scene, thanks to that light and those fringes and other hanging objects, which give depth.
