Love the image, hope to be blessed with the vision someday as well.
Two things I note, for what they are worth. I would add just a little canvas to the sides. I like the vertical, but it seems a little cramped to me with all the plumage, like a bride in a narrow hallway with a full vail and train! :D
Second, I would cut about 1/3 of the open area at the top.
Geez Fabs, I wanted to find something to critique on this...but all that comes to mind was "wish it were mine"! Those soft, wispy plumes against that stunning BG just make this one a killer.
I love it but I think that it needs some levels adjustment in the midtones (1,16 works fine). The egret is a bit tight in the frame and I think taht more room at the left and at the bottom would produce a better composition. I know that you are trying to get a very dark environment and I like th eidea. De verdad que me dan muchas ganas de visitar ese lugar :-P
