I really like this but as an abstract not a picture of an octopus.
I feel that the contrast and sharpening have been overdone but with a softer feel this would be a really winner as a result of the lighting and the texture.
A touch lighter as well and blown up onto canvas I think this would make a a great modern abstract.
In my mind the impact comes from the colour and texture and recognisable shapes are not needed.
This sort of shot is where photography and art crossover. I think I am disagreeing completely with Photobeat (sorry) but I don't think a picture needs to tell a story or show another world. It can stand on its own two feet as a piece of art.
I'm possible biased - my lounge is styled in a contemporary fashion and has three original abstract canvases on the wall. One is however loosely based on a picture I took of the skirt of an anenome (not painted by me I hasten to add).
I would say keep on experimenting along these lines.
