It is nice to see when people have "an eye" for these kinds of little things, such as the feathers forming a still life of this kind all on their own, in the way they fell.
I think you focused well and chose a pleasing DOF for this photo, and aligning the one feather with the bottom of your frame, having the other cut a diagonal line through the picture are nice elements.
The conversion could have been better. It is a bit "pale". Flat - i.e. lacking in contrasts. Nothing you could not still work on, since this version of the photo (b&w) is the result of some pp work, too. So why not just add a bit more pp work to it to make it stand out more?
