The first feature I would like to see is the ability to reload a revised "photo" to an existing face model.
This would be an enormous time-saver, since otherwise one has to start from scratch on face-fitting each time one decides to refine the image.
I assume that one reason you don't offer this already is because two photos of different resolutions won't automatically map to a single 3d model.
However, if you encode the width and height of the original photo at the instant the model is created, you could check the dimensions of the replacement photo (2D cel drawing, actually!) and accept it for refitting only if it's an exact match.
I'm actually hoping you might see fit to incorporate this in a point-release...?
Note that I do not favor the alternative of offering a makeup-room in which the user paints on the face model. Technically, I think that would be overkill. Besides, one has so much more control in a conventional photo-editing application.
Thanks for listening. :P
