Launcher's looking good! :)
Speaking of missiles, I just got one of these, which may interest you:
It comes out about 21cm long, which is about 7.35m in 1/35th scale, i.e. in the same ball park as a Pluton tactical nuclear missile, longer than a Lance but shorter than a Scud or FROG, and you could easily lengthen/shorten it. Look good on a TEL, wouldn't it?
