A bit tight in the frame to my taste Danny, just a litle bit of more room at the left and right. The BG and light are fantastic and I know why you like this species because last year I had the oportunity to photograph KF and I can´t wait to repeat the experience :-)
Wonderful shot, really nice BG, perch and of course bird.
The fish is the icing on the cake.
Seems a wee bit tight as far as cropping, a bit more space all around wouldn't hurt.
Outstanding work Danny. Exposure, lighting, and background are all great. I'm ok with the amount of room on the back, but the front definitely needs a little more room. Nice job.
