The arms turned out fantastic, Bart! Yeah, the drop boxes could definitely be raised a bit and moved toward the rear.. in a perfect world they should look like the diagram below.
Not to add to your list of woes, but I have 2 other easy to remedy suggestions if I may.
1. In the first pic it shows the top of your ABS belt covering the bottoms of the ab/button panels, but in the second pic it shows it sitting a little low. Not a requirement for Basic, but since the snaps that connect the cloth belt are already set, what you can do is use a piece of industrial Velcro (bottom photo). I use this same method. I borrowed Adam's pic to illustrate this.
2. In the second photo, I noticed that you have a point on the inside of the top of the forearm. This will poke into you, especially since while trooping we have our right arm bent in most of the time while carrying an E-11. I would suggest taking some sandpaper and rounding that off. Trust me.
On a side note: DANG I'm glad to see what a great job you did removing all those return edges! Keep up the great work, Bart.. you are doing fine!
I still say we need to start an OCD support group here. I'll be the first to sign up..
It's called the antecubital fossa, but elbow armpit sounds perfect. I am so going to steal that phrase, Adam.
