Yes, I do like the band. In fact, I love it. It is by far my favorite band.
Sort of Steampunk-ish...but more Grey. Dieselpunk, perhaps?
For our game, we plan to have at least one Zeppelin, so I thought that I should get some practice. I'm fairly pleased with the balloon and the lower body, my main qualm is the connection between the two.
That overall dark grey colour really does make this MOC look as though itwas cast from lead. I like the stretched Lego sphere gas bag, though perhaps you could have extended the top plates by one stud on each side for smoother corners? I love the term you've coined, "dieselpunk". Trademark it quickly and make your millions!
