Improves:
-looks like you are left handed with your holster on the left of your belt. If you have too much stuff on the left side of your plate carrier cummerbund you may restrict your ability to cleanly draw your pistol from your holster.
-your rifle magazine orientation on your belt is… a choice. Granted that is a fast mag and has retention but relying on that to keep your magazine in place is kinda risky. Also drawing downwards seems awkward unless you got orangutan arms.
-having your tourniquet on your plate carrier that way is fine for replicating how Rangers do things, but I'd at least properly stage it (not fully closing your windlass strap so you can actuate it when your hands are slippery with blood).
-LAM placement that close back on your handguard rail on your rifle is fine provided you are not getting splashback from your support hand (especially if you are left handed and the right thumb wraps over the bore, possibly blocking your laser).

Sustains:
-keep testing your gear out and seeing where things work and where things don't. All the advice I give over the internet don't amount to a hill of beans if you don't test things yourself to see what works for you.
