Sci-fi, Space, maybe. But not medieval, or fantasy style..it's too 'flat' in vital areas. Tthe idea of armour in those days was to present a 'glancing surface'..to direct any weapon hits away from vital areas..and to avoid areas that would 'catch' a point and allow it to bite in. With those ribs..and some of the embossing on the chest..you've created spots tha will allow nasty pointy things to concentrate their force and penetrate.
