Nice singing pose, and good exposure on this black-on-white situation. I wouldn't have minded seeing the subject a bit smaller in the frame with more perch showing, but still good as is. The big reflection in the eye could be reduced in post just to make the eye look less "glassy". Overall well done!
Hi Dave, excellent exposure on those blacks, and well timed to get the open beak for the calling pose. Dave, if you have more cat tail, I would show more of that, as per Dan, and then you could crop a bit off the top. Make him sit higher in the frame.
