I've looked at this at least three times now, and I still don't know if I like it or not. I think I'd like to see at least one of the bird's heads. They definitely stand out against the background color you've chosen.
I like the detail in the wings but it is a bit disconcerting that I cannot see the heads. I am also not too fond of the sepia background, it just doesn't go with the colour of the birds. But I do like the placement of the birds in the frame with the branches in the background.
Excellent!! The succession of 2 birds in flight and the perspective of flight in the frame is well taken /seen. The b/g is complimentary enhancing the birds..
I've seen the headless horsemen, now the headless birds. Would be really cool if both were in focus but I suppose more dof was practically impossible. Strange color to the background.
