Completed Space Marine Costume

I love the costume. Looks amazing and totally sells the idea that you are a real 8 foot space marine. I have a suggestion to something you may want to try since you said that hands don't move. Why not try to use a wire pully system like the what you would find in a toy extention arm? you could make the the inner pipe you use twist lock into the outer forearm part. The hand would be able to twist left and right at the wrist any longer and it would make the arms a bit more unruly to handle but it could give you some articulation in the fingers. Love the costumes looks great and I wish I had one.
