Nice work and welcome to the boards!
I like that Hoth Polar Scout, I would say he could use some more detailing, but then again, as a vintage figure I think he looks fine. I like that you made his armored pieces a slightly different color than his underarmor
Roron Corrob looks great, I like the paint scheme but he needs a lightsaber!
Garindan looks cool, especially since you sculpted the head.
I also like the Sandtrooper and Droids Fett, they both turned out great.
Overall, a great set of vintage customs. It's refreshing to see customs made using vintage figures and your customs definitely have that vintage-feel to them.
