I really like this image James, the placement of the Rock and the position of the feet are fantastic. The water in the FG looks great also.
I feel the same as Maxis, fill flash would have been very helpful here to balance the tones. In this case with Quick mask or layer mask or better yet to converted RAW images you could easily darken the BG a little and lighten the bird a little to balance the subject and BG tones.
Strange that the feet look as if fill flash was used.
