Very soft, effective back lighting, complimentary colors.
I might consider moving the bird a bit to the left in the frame. I wish there was at least a little backlighting on the head area, just to add that last bit of interest.
Manos....very very artsy. Loved the pose. I liked the fact that it is not a pure silhouette. Having said that, a little boost in contrast might make it even more powerful.
Interesting preening pose Manos, and good to see the backlighting through the wing. I agree moving the egret to the left will round this image off nicely.
