Hi Jim, this shot is technically perfect. I shoot humingbirds too. But I use flash. I like the fact that you did not use flash here and got such a fine result. The lighting looks real nice. I am surprised in fact. I would think you would need bright sunlight (which I hate) to get the shutter speed you used. I want to try to go without flash myself now.
Every thing is working great here. Comp, exposure, details and subject are all working great. Well done image.
Excellent image considering working only with natural light.
I agree with the others that this is an excellent image with all the tech stuff spot on. I don't want to be the Scrooge here, but I wish there were a flower or leaf to anchor the left of the image.
