Also looks like the chest plates may need to move closer together to even out the spacing around them and the chest diamond space may need to be a little larger as the diamond seems bigger than the cut outs. Other than that, it's looking fantastic and I second what Corriban said about the gaunts. Plastic piping and/or guttering is popular over here in the UK for easy clamshell gaunts, not sure about where you are but ours don't need much reshaping.
