Lovely capture, but the 'diagonal' connection seems stretched here. Yes, I see the line of the bird from one corner to the other, but skewing the composition angle would have been compelling & more in the spirit of the challenge. Focus seems a bit soft around the head, anyway.
I'm pretty much a newbie here, though, so take my comments with a grain of salt - just 'cause I'm being critical doesn't mean I think MY stuff is doing any better! You'll likely lap my submission... Good luck!
