I like the 'little bird, big world' mood. Angle, details and BG look good, too. I wish for a bit more head turn toward you and would clone out the dark half-moon shaped thing in front of the bird's legs.
Very nice Adams. My first thought was the Little Bird-Big Lonely World thing - as others also noted. I like the comp, exposure, and narrow DOF and agree that the "half moon" needs to go. Well done.
Very nice, interesting crop and composition, a more horizontal pano crop
might be also possible here I think. I like the light and feel of fragility
as others pointed out.
