I like how the perch fits in the frame, bright beak and loose composition. I would clone out the three bits suspended in a web because the web connections aren't totally visible. The throat chest area looks a little bit bright. Nice image David.
Hi David, I like your choice of comp with the diagonal flow of the reeds. Well timed to capture the open beak. If it was possible, moving to your left would have given you even light on the bird.
David the eye stripe and the orange mouth together with the song will help identify the sedge v other warblers.
Lovely pose and composition. I may be tempted to lower the brightest highlights on the neck if possible, I suspect it would reveal a little more detail.
