Nice timing! I was just mulling over airship ideas and feeling a bit unsatisfied with the options I had available, but this looks like it just might do the trick! And I have a neat idea to make it even better: Take just the balloon / blimp part and attach it to the top of the old parallax pirate ship in your free assets collection -- since you gave us a version that doesn't have the sails, it's as easy as simply pasting it on top of the masts! Gonna give that a shot when I get some free time to see how it looks.
