I'll be the first to tell you I'm a noob in COSPLAY, (which means I'm a beginner at this) my start at this was extremely cheap and not so typical. But that's what I liked about my PREDATOR's path. I knew that my NEXT suit was going to be BETTER then my first.
I like watching PREDATOR movies and comics, toys and everything about the PREDATOR evolution interest me. Your idea of making your first costume is everywhere, just take a few and make it your own way.
I'm sure you'll do fine, if you need any help i'll let you know

happy hunting!
