So I've done a bit of a Hal Jordan - Green Lantern Redesign.
The suit is still generated by the ring. It comes in two different textures, a matte black and a glossy green. There is a series of veins of energy that run through the suit generating it.
I've gotten rid of the white sections of the uniform and instead turned them into a light giving section. I also thought the badge could be more over the heart, to be more uniform-like in an intergalactic policing capacity.
I want there to seem like a system for the ring to generate the uniform itself, fairly easily. Like a template that could be applied to any humanoid alien to adapt to easily.
I wanted the green energy to fizzle and smoke off whatever is being generated at the time - flight in this case.
I also didn't avoid facial features of Nathan Fillion.
