You've just come out with Halo 4 style Elite rangers. Great figs, BTW.
My suggestions is that you make these in all white as well as all orange variants. You could have them in the armor set packs as you did the new Zealot and Ranger set.
The reason why is that they would tie in to the Elite rangers from Halo Reach. Almost all of those were white. The rare exception is the orange Elite Ranger.
In order to see this one, you had to be at the right place at the right time. This often meant 'speed running' through a mission to find him.
