This was a big project for the same cosplayer I did the Dinashi illustration for; his void elf assassin's core look. The project was fleshing out his character from the ground up, starting with the helmet to get the general idea and then building the rest off of that.
The large number of concepts for this project is due to the fact that we were starting from nothing for finding his character's nature. One of the stipulations though is the paint color; in real life he's using an oil-slick-blue automotive paint that has a color changing effect, so I tried to translate that to the concept art. There are two "final looks"; one where the silver metal is plain, and the other where he's applied a Mokume Gane effect to it.
It was a challenge to make it feasibly buildable but also what he truly saw his character as, but I'm happy that I pulled it off!
