Artillery / Lifta Wagon

Ok next piece is going to be the lifta-wagon. It's an artillery piece based on the land raider chassis. Got a few ideas for this but it's essentially evolving as I build. Which is the way I prefer to work, even if it is a little scary at times!

Hopefully it'll make sense as it gets more complete. The last picture is the idea for the lifta-droppa itself. A pod from Anakin's Pod Racer :). And the top off a bottle of sealant. Again I hope it'll make sense. If not no doubt I'll shoot off in a different direction, as I tend to do.
