Hmmmm, I think the armor looks fine on you.Once that vest is weathered up(right now it is just really bright behind the armor.), and the gauntlets and girth are added, i bet it looks a lot better.
the cod looks fine to me(you do not want it to look to big and bulky) and the top will be covered with the girth belt anyway.
My thing is that you should be able to move your arms inward without smooshing the armor together.
I think you look awesome.
