I agree with Artie that the leaf is pulling your composition. Other than that, the composition is excellent. Those little yellow mouths sitting on the third are perfect.
Is that a shadow of your head I see in the bottom middle of the frame?
Really good lighting in this Chris...the intruding leaf on the left can get cloned out and crop some of the right it is pulling your frame....but overall well done....
Oh Chris, once again, I'm very envious. I tried so hard this spring to get these same kind of little creatures on film. They were in a hole in a tree, I could see their little beaks and all, the pics came back so underexposed all you could see were little white dots. I like to think the little ones in my back yard now are the same ones. I can see yours are out in an open nest, so.....It was fun trying tho.
