Do we know if the R2 Builders Club are responsible for the weathering also? or just building him. I'm not knocking their work by ANY means, and I'm so excited and proud for them that they were able to make the ep. vii R2, but the weathering job does look a little too airbrushed to me. Instead of having the appearance of dirt and grease building up in the natural grooves, it looks a little too even and intentional with the brown misting.
Don't get me wrong, I think it still looks fantastic and I'd gladly take this ANY DAY over a CGI flying R2 with go go gadget oil slick and rocket boosters.
