Looking fantastic, Shane! I realize that you haven't started on the strapping yet, and the areas mentioned below will take care of those. You are definitely on the fast track for Centurion, sir!
These would be my suggestions:
1. Having everything level/symmetrical is important for an ideal look. The bottoms of the bells and wrist openings are presently at a different heights, but no biggie, as once you install the straps you should be golden. I would definitely suggest making sure the tops of the bells touch (or are VERY close to) the ABS shoulder bridges. This will also bring them in closer to the chest and back plates.
2. The gap in the back/kidney connection should be reduced. This should be a matter of just dropping the back plate down a little. It's great that you haven't done the white shoulder elastic yet, as that will make it much easier.
3. The rear closures on your calf pieces need some tweaking. The yellow boxes are where the cover strips should go. It appears that you have plenty of wiggle room on the left one, and the right one may just need to be lined up.
Keep up the great work, and keep those photos coming!
