Awesome video tutorial, Spud!
Double thumbs-up.
Don't know if you have them in your spare parts box, but you may want to try some 1/35 scale modern mag pouches as accessory or ammo/battery packs on the belt of the female Mando. They also work well as upper-arm pouches, possibles bags, etc. I think that small details like these enhance the overall appearance on military figures and mercs considerably.
A casual viewer will possibly not spot them, but other customizers surely will.
If you need some, shoot me a PM as I still have a lot of figure kits around from my military figure modelling days.
