Seeing the creation little by little was rewarding. Dragons have always been majestic mythical animals and this is no exception. You have excellent final result. I'm pretty impressed It would have been great to read step by step how you achieved that result and also the program you used.
Tilt Brush is the program. Oculus Rift is the hardware. I imported a 3D dragon and with tilt brush painted every scale, star, cloud and rock you see in a virtual environment. When the sketch loads in Tilt Brush it reloads each brush stroke, so what you are seeing is a step by step loading.
