DecalsI actually ended up using all the decals, but somehow one of the bottom Balkenkreuz got partially ruined (the tips pointing towards the hull). Don't ask me how that happened. Other than that the damn things went on decently, even the two-piece swastikas.
AfterwardsAs you may have noticed, I had left some details unpainted, maybe a bit sillily. I just hadn't remembered to do those before I went applying the gloss varnish. So I painted the wingtips red (VMA 71085 Ferrari Red) and then used that to the rocket's nozzle as the instructions dictated. Then I painted the steering vanes black (VMA 71073 Black). Then I deviated to my own direction by painting the edges of the rocket's nozzle metallic (VMC 70863 Gunmetal Grey) because they looked better - or made more sense to me - that way.
With a matt coatI took a few photos after the matt varnish layer (Vallejo 70520) had dried, from various angles. I thought that I should've washed it at some point, but as I hadn't thought of it then it clearly wasn't that important.
Finally I set the missile on its launch pad to pose a bit. As a whole I thought it was a bit underwhelming compared to something hefty, a heavy launching facility or something (the Meillerwagen would've given a nicer base for this). Or maybe my image came from the flat backgroudn of the cutting mat that really didn't work as a substitute for a forest clearing or something.
