Hey, I am working on a Robot model for my hard surface and organic modeling class but I'm not that good at concept art. If you are interested I can send you the specs of what I want/ need for him. I will make sure to give you credit for the concept, and will credit you for the final since you are helping with a major part of it.
The overall idea is an organic robot mechanic. So comment or message me if you are interested.
Thanks..
