Lance this is lovely. One thing I see is that the white of the head and neck are not quite as white as the body - they have a slightly gray overtone. Did you think about selectively lightening/brightening that area of the bird at all?
And did you hand paint the eye and beak or use a quick mask?
Love those long black legs...You really have done a nice conversion here. I do think whitening and brightening the neck and face will make those spots of color even more distinctive but it's lovely like this as well.
