Good composition but the bird is very soft and needs sharpening. The back view is fine, but the head needed to be turned a bit more toward you., The cut off end of the perch makes me wonder if you placed the perch for birds to land on. If so, try to put up a perch that is more photogenic and does not have a cut end. Try to place it where the background will be a single clean color. The birds will readily land on a perch you put up in a better place - especially if it is near a feeder.
Thank you Linda, I did not put the branch there but in any case I think I can use your advise and may be put some nicer branch! about sharpening I will tell you that I agree with you, but with this hummer in particular the feathers are very soft and I donīt know how to fix it. I will see what I can do.
