Hello there, my first post in this amazing and helpful forum. Few weeks ago I made this version of Hal Jordan as a quick Speed modeling in Rhino.
Here is the process:
Part 1 Main shapes
Part 2 Posture and transitions
Then the renders, about the glow I made it later in photoshop.
The ring material was a dielectric with emissive label on top of it using the curvature texture as mask to highlight the edges.
