It's off-center, but i think it could be a bit more interestingly shot. The lighting is dramatic, feather well-detailed, but I think the light at the bottom (glare?) is a bit too bright.
Just one feather ;) Great idea, meets challenge. Love the focus and the fact you included a vertical feather in a landscape format photo. DOF is spot-on, really like just how smooth the background gets toward the top. Two things that could be better are the blown out white soft bits of the feather (I know how hard that's to control, I've photographed feathers myself) and - something that's easy to control - the two out of focus longest bits of grass in front of the feather. I like that there are some in the front, but those two tall ones are just that (IMHO), too tall and detract from the feather.
