A lovely fellow, excellent HA and angle on perch, pleasant BG, nicely scaled perch.
The bill and eye are sharp, with some softening of the back of the head. I suspect the point of focus was just a bit more anterior than the head, based on the sharpness of the perch in front, versus behind.
If it were mine, I might adjust the luminosity of the background to a slightly lower level, to help the hummer stand out more, but it is very nice as is.
