A classic singing pose and a strong diagonal perch make for a good all round image. Lighting has been handled very well, with some good detail in the white throat. With regards to the comp, I would have placed the bird bang on the upper left third. I would also give it another round of sharpening. So the very minor nits aside, it's a good looking image, Jonathan.
Nice looking shot and I really like the BG and the setting. Great looking singing pose also. I agree with Andy about the comp and the sharpening. Nice work.
Love the calling pose and the lovely light and BG. I am seeing the head is not as sharp as the rest of the bird and could use more sharpening. If this is a set up you are going to reuse, I would consider taking off some of the right side of the perch.
Lovely pose captured and the BG is superb
i may even give it a vertical compo if it works well
the singing pose keeps the viewer on the bird, very nicely done
