I like the green and silver guy, he rocks. As far as repaints go tat one looks very good. I noticed a green sharpie in the background is that what you used?
The second one is shaping up pretty well. The add ons look very good, I like the leg armor. As far as painting goes, if your looking for a sand gold color. Walmart has that very color for $0.44. Just check the Apple Barrel acrylic paint section over in crafts. These are the paints that I use. They also have something called Antique Gold that looks really good too, I was thinking about snagging that color myself.
