Here is my custom:
I did the same thing. Here is a quick shot of themI successfully tried the pencil upgrade on artoo. Then, minor customization on my sandtroopers. One is the normal one out of the box, the other is the same as the first one but without the pouch/ammunition thing on his shoulder, and the other is without pauldron or equipment, as he appears in the ANH hangar scene. I decided not to paint any pauldrons black or white. Ill just wait for those variants to come out, hopefully with different accessories.
