I can't say anything about the ties that hasn't already been said, good work. What I do notice is that most of your heads have the eyes painted shut. Cleaning with a heated bodkin is the easiest way at this point. To not paint them in the first place I use a small pair of spring loaded needle nose pliers. Hold the bend of the hook and hold it over the heat gun til it's right, then grab the eye and dunk into the paint or fluid bed, and return to the heat to glaze it and set it aside to cool. Since I began this I haven't clean one eye yet.
Creativity is just intelligence fooling around
