Nice and sharp and i like the view and BG.
The flash is subtle and well done.
I would crop to just above the signature and lose the signature.
They are worthless really and if you use one, it should be very discreet.
Thanks for the feedback, I can lose the signature easy enough. I wish I had a blind, I shoot from a folding chair under a tree. I may try a blind in the near future, I have a friend who uses one quite a bit and he has invited me out to shoot with him.
I hope to move up to a 500mm before next year... we'll see.
I love the pose, perch and background (reverse clarity...I'll have to try that). I like that you composed this vertically with the subject up high but I agree with Randy about moving it more to the left.
A blind does make a big difference, and there are some light and inexpensive ones out there...
