Mike,
I know of and have seen images of Ron Layport’s work, so I can see the inspiration that it's given you.
I have two problems with this piece though, it's too stylised to be realistic and too simplistic to be impressionistic.
To explain better, I think it's based on a Heron (curl of the wings, shape of the beak) but as you had a premade form (teapot body) to start with, all you could do was carve out and create the form of the bird within the shape you already had, so could not really work.
However with your skill in creating hollow-forms, I think if you worked from as blank, creating the correct shaped vessel to begin with, you could create a great carved form.
