Very nice detail on the hummer, nice background. I'm guessing based on your comment that the LRC red tint is from the feeder? A little head turn would have made this even better.
The bird looks super sharp with a beautiful and colorful side view. lovely BG as well.
I'm not crazy with the squre format and the bird is too centered (for that scene)
Beautiful crisp shot, wonderful exposure, I think a little more off the bottom would
make this a stronger composition. A little too centered, but a great capture.
