this took too long lol my apologies to improve rendering I'd suggest trying bigger, harder shadow edges to avoid a flat/pilowy/muddy look and help the 3D shapes stand out And for general improvement make sure that the planes & 3D understanding of the face are correct :D im still working on memorizing the human face planes lol (also for canine teeth there are a ton of great references out there! I'm actually considering getting one of those veterinarian replica jaws to use as reference material lol)
