Love the look of this armor style! Yours is coming together very fast!
Looks like the top of your left chest plate might need to be shaped towards you a tad more, and the spacing of the chest fangs down near the ab plate may need to be formed closer to your body. If there is a way you can give us a shot from each side that would help with providing any comments on spacing too.
If you have a really hard time crossing your arms in front of you, or holding them out straight you are getting poked, a trim may not hurt. They do look like an okay size to me though. Maybe if you were to decrease the angle going to the point from the top edge on the side of the chest plates? That looks like the part that would poke you.
The only other critique I have is that your flak vest may need to be tightened up a tad. In the pic with your templates it looks a bit loose.
Excited to see more work!
