I think the tail on that thing is pretty good actually...is this gondola going to be attached to the bottom, or the top of the balloon? Maybe, actually, you can just cut segments out of the tail to give it a winged appearance...perhaps by lining up cylindars along the side of the ship that meet at the back, so that you can slice out parts to give it like a dragon-wing or bat-wing type of shape...if you know what I mean.
