Green Lantern 2814.1 - Hal Jordan.
Did this one in Daz Studio and Blender with some Photoshop post-work. Rendered over at RenderStreet.
2400px x 1920px at 5,000 samples cost me about $3.46 (US). I went beastmode on the samples because the SSS in the skin shader and some of the glossy material I decided to use was causing serious fireflies. Tried every other trick in the book but in the end I opted to brute force it.
I went back and forth with making the chest emblem glow too like it does sometimes in the comics these days. I ultimately decided it was too much with the ring already glowing though. Maybe in another image...
