Nice pose, looks quite regal atop your feeder. I would clone in some colour in the white areas bottom left and top left. I was gonna suggest fill-flash for this situation, but that's hard to achieve through a glass window...it could be worthwhile to get yourself a blind to setup in your yard and photograph directly outdoors ;-)

You have a very nice pose.....especially the eye contact. I am always amazed at images photographed through glass when there's a lot of nice detail. I've had Flickers in my yard but they have never come to the feeders. I'd sure get some nice perches up with a blind......or photograph with the window up but a cover except for the camera/lens and take advantage of all that comes your way.
