Praetor Suit (beginner)

[Paszcov]

I’m just now thinking of getting into cosplaying and prop making and the first actual “armor” I wish to make is of the doom guy/slayer from either doom 2016 or eternal.
I have the body type for it and I was wondering if anyone has any suggestions for creating a detailed work like this?
Should I stick with cheap foam or should I move up to something with a bit more grip? (I’m on a restrictive budget so)

first look at the style you want (try game skins) then build cardboard templates to judge size/fit this saves on foam then when you have the carboard template you like convert that to foam
