Really good. You have the same idea I did for the robotic arm. I'll have to post a shot of it later, I'll let you know. Check out my Halo folder if you haven't. Your customs are very good, and I'd love to know what you think of mine. Also, the ODST helmet turned into Air Assault works very well, good idea.
