Incredibly Cool Original Sci-Fi Character Designs

Check out this amazingly cool set of sci-fi style character designs created by CGHUB artist fightPUNCH. The characters are loaded with all kinds of mechanical robotic details. There's no information on what these are for, but I imagine they are part of a personal project the artist has been working on. I would love to see a group of cosplayers take these designs and bring them to life, because they would make for some really badass costumes!
