more than ... times i shot it..ffff
the sharpness looks pretty good, but I think the b/w - sepia tone doesn't help very much -- the feather almost blends into the background/sky. Maybe try a color corrected color version? Or go for a darker sky (http://raymondshay.com/tutorials/ColorToBW/index.htm) to make this one outstanding. All the best!
Beautiful shot.
The B/W works really well here, especially with the clouds, however maybe you could pull up the contrast to make the feather stand out more?? But Well done
