Post Apocalyptic Survivor Costume

I am Christian. I am in the eighth grade and I've always been fascinated by the numerous survivors of Hollywood apocalipsis. The ideas started when I first made the chest plate for the armor, the character isn't based off of any specific character but came from my own imagination and mind. The entire base of the armor is crafted out of EVA foam using techniques from YouTube and other makers. To weather it and make it look like brushed Steel I but silver paint on the brush. And Touched the parts that would get rubbed and touched the most. The total cost for the costume was somewhere between $80 to $90. Repetition is one of the most important things.
