Hi trooper , nice build was it a commission from RS ? .
Shoulder bells look to be sitting a bit high , pull these down and maybe shorten the elastic from bell to shoulder strap. Moving the elastic conection from bell foreword on the shoulder strap a bit would help close gap between chest and bell.
Hand guard elastic to sit on palm of hand , not behind thumb.
Sniper plate behind thigh bit of foam either at front of shin or at back of thigh should help with that and maybe try pulling shins down a bit.
You could paint TD clips and butt plate snaps and any of the other rivets and snaps black to help improve the overall look.
Good luck with your local garrison you should be fine.
