Working on Arkham Origins Deathstroke cosplay

Hey guys, this is my first time making my own costume so go easy on me. I'm trying to get materials and i'm just going to list off some of the materials for the armor and want your opinion of whether or not I have everything or if I need to change something.

EVA foam
Plasti dip
Rust-Oleum Metallic spray paint
X-ACTO knife
Straps( for connecting the armor pieces)
Hot glue with glue gun

Do I need to add anything or am I okay so far?

I would get a hot knife instead of a regular x-acto knife. It makes cutting the foam easier, and it tends to make cleaner cuts I think.
