I thought the movie was good! But can always try supatroop as hes doing a bust run i think or balboa the stallone bust expert!! in regards to the shoulder foam pep and then coat in resin could work! and it could make an awesome 1:1 manikin display!
Great job on the helmet!
I got a pep file of the shoulder armor (stallone version). Andrew made them for me. Check his site CS Props. I think you can get them from him, if you like.
