I haven't tested the color set or even seen it in game, but it looks like there are too many of those orange colors. They all look about the same shade. Although, I don't know what you would replace them with, you may want to think about that. Maybe add some more browns and greys, they are always useful.
Other than those criticisms, I would rate this a 7/10. Probably gonna download this tomorrow when I get on my computer.
