The light really worked well for you. I'm surprised that you got such sharpness at 1/60-sec., but it's wonderful. Using f/8 gave you all the DOF that you needed and the Siggy's bokeh is creamy smooth. The green in the bokeh is a nice compliment to the bird's feather color and the overall image. Head angle, pose and perch are all very nice, so I have no suggestion for improvement.
