Those figures look as good or better than the ones that come with the V-1 sets (which already have noticeably improved facial details from the switch to 1:30 scale). The two officers are clearly SS based on the cufftitle which makes sense because the SS took over administration of the V-2 program. However, and it's hard to tell, but it looks like they may have rectangular Heer/Wehrmacht collar litzen (stripes) - shouldn't they have standard square black SS collar patches with the rank on the left patch and "SS" on the right? It may just be the angle of the photo that makes it difficult to tell one way or the other.
Also, the tunic of the officer in the middle seems a bit short below the belt for a German tunic, but it is possible that since he's an officer, it was custom tailored for his proportions.
