Can't tell if this is intentionally desaturated, not against the idea, but personally would like to see some more motion/feeling with the dog (who is good looking and appears to have definition and strong lines). Although, getting him/her to cooperate is likely easier said than done!
Interesting. The composition is perfect but the colors look a little drab to me. Also, that looks like trash in the grass that would probably improve the photo greatly if it were picked up first. ??? The title and imagery are great!
