WElLL DONE!
The armor is all really nicely weathered and aged
If I might make a suggestion -- but the loincloth fabric looks pretty new in comparison to your armor.
I had the same issue on my costume.
So this weekend I actually took my pred loincloth material outside - gave it a few quick misty sprits of black primer to dirty it up on the lower tips - then scratched and pounded the ends with a rough brick in the stony dirt. I pounted the ends and dragged the brick down the fabric the way you would if you were ironing - or as if the kids were playing race car with the brick down the fabric. The sharp little stones in the dirt and the rough brick really chewed the fabric nicely.
All and all it took about 5 minutes to do -- It helped put a lot of moth eaten looking tears and natural looking age and to the fabric to match the age of my armor.
Perhaps you don't want it as lived in as mine - so you may just want to age it with paints
