Not exactly a shabby score for FS... Amazing capture. You have great contrast, depth and sharpness. However this all makes birdy's head blend in with his wing. Maybe a little softening on the far wing would help - a post hoc dof adjustment of sorts. As others mentioned, the light blue-gray background might have been an issue. Perhaps opting for all sepia and then torquing up the golds and whites might have warmed things up a little, although it would make it less clinically accurate.
BiF photography is incredibly difficult and technical. Yes you can hold the shutter down and fire away but in most cases this rarely even gets one good shot. I'm surprised it didn't do better. No wait, it's not a DPC landscape! :) Keep up the great work.
