Wow nice! I wish I was your son I have to make my own Rookie armor because my parents don't know anything about Halo.I've made my own gloves and I'm using my shin/knee pads for the leg armor since that have straps and some black parts that you put your leg through I'm also using my elbow pads for the lower arm and elbow armor but I'm gonna cover both in cardboard so it can look better.Also how old is your son?
