Works a charm. A nicer and higher-res texture should be painted on top of the guide. The guide is 1K (1024x1024 pixels) in texture resolution, which isn't tiny, but because the UV map of the face is quite small (it has to share space with the large neck) 2K would allow for more detail.
Dragon model and pre-made animations made, woo!
Just need to load it all (UV, animations, etc) into the game environment.
