Well Ed I know I'm supposed to cheer you on
I shal have a little muse on this one- it was originally meant to be about the glowing gut of enclosed water with a little point of bird action, but I concede it has got a bit out of hand what with the tiger skin rug
If you headed in the direction of a tiger skin rug then there was a reason. I'd pursue that direction and see where it leads.
there is a good idea Ed...and now that I get to see the shot, think about how beautiful that right side of the channel is, not a straight hard edge like in the painting so far, by using the more dancing line it makes I think you'd add a great deal to the shape of the water and the pleasure of the eye to see it.
