It looks great so far, that chest piece and bracers look incredible.
Have you ever considered making a duct tape dummy of yourself so you could shape the armor to your body better? You'd still need the templates you make with those pep files but it would help to fit them to your body a bit better and make some adjustements as required.
I see you are mostly finished building now but it could be useful for other projects later, plus, you could have you suit up for display after too, just stuff that dummy, make it stand uprightwith a metal rod or something and Voila, a homemade display manequin.
