Fantastic calling pose and I really like the character of the reeds and the diagonal effect.
Exposure looks nice. Appears as though you could push sharpening a bit more to my eyes, particularly on the subject.
As much as I like that you left room to the left for the bird to look into, I believe shifting the subject and reeds just a touch more left would give a bit better balance. It's one of those maybe, maybe not type of adjustments but worth a try IMO.
Suer image, Will. Calling pose is very nice, and the perch really cracks in the gray surrounds. I can hear Brian's comments about more sharpening on the subject, but you might be up against it with IQ (because of the 2x) as the upper breast and neck are looking a bit smudgy/crunchy as is. I do like the gripping feet!
Bird, pose, perch, and background all look very nice! What an appealing frame here Will. I'm sure a touch more sharpening would do well for the fine details, but looks acceptable to me as posted.
