First problem encountered with this resin add-on, thanks to resin shrinkage, the forearm covers no longer snapped into place properly, and the thruster flaps didn’t close anymore.
Overcame this by cutting the resin part in 2 and trimming up to the panel line, then doing the same with the original part. the 2 marry together at that point and everything fits together now, joy.
Also test fitted one of the shoulders, no problems on that one. although bizarrely even with everything tight and closed, there is a consistent strip of exposed frame that concerned me at first, but turns out is part of their design.
Last pic is just the little lighting setup I use for these little pics, I cant recommend these little softlights enough for toy photography.
