This is adorable, Jim. I like how the soft side light brings detail in the plumage.
DOF is of no concern to me here. It looks good to me.
You may want to mask some sharpening off his bill.
After a long hard day, I just saw this image and literally laughed out loud, Jim. I love it! Undoubtedly the funniest shorebird image I've ever seen. Great low-angle capture, perfect HA and EXP and BG, and DOF looks fine to me. TFS, you made my day.
