I see ok.
TM when I look at your build here: http://www.whitearmor.net/forum/topic/8240-the-right-hand-side-snap-and-chest-and-back-question/page-2, it seeps you used snap plates at the shoulder, then a middle snap to conventionally connect the shoulder bells.
Additionally, on that same photo, it seems that your breast plate is overlapping your abdomen. Is that ok for my son's armor?
