I'll be honest I'm not sure I have much to contribute to the discussion here but I absolutely loved the Rogue One costumes & props at Celebration, I felt like they were all spot on, perfect ANH era look
I'm no expert & it wasn't until I was right next to the Stormtroopers that I even noticed the subtle changes to the armour & helmet, I liked them I think they make total sense whilst retaining the classic ANH Stormtrooper look to all but the most observant viewers. I'd love to have one of these new helmets, the cut out stripes look really good to me
For all the smartening up of the Stormtrooper Armour itself I enjoyed how rough & ready the casting of the E11 blasters actually looked up close (very OT)
I also liked how the Death Trooper & Shore Trooper blasters were basically variant E11's
I also though it was very nice that they've used the SE-14 blaster as the Death Trooper sidearm, they didn't need to do that it was a cool touch to re-use the design
I think the designers & builders on this have paid real respect & attention to the original films in making the costumes & props fit
things have been pretty quiet for me prop wise this year, I enjoyed TFA but for some reason it didn't fire me up to build & paint props but Rogue one is making me want to build & collect again.
