Thanks for your comment L.A., I'm glad you like the MOC. x)
You're right about the tube, its position doesn't fully satisfy me, but I don't really have any other solution. x/ Maybe I should simply remove it.

Amazing work, dear, and hope you will come up with more of those machines! =D
I hope so, but it won't be easy, it might be easy to build a battle machine, but it's much much harder to find an original idea and a good concept that would make an interesting MOC / set.
Epic and brilliant concept, and also adaptation! A massive machine, well covered and with an unique idea! I don't know how high can go the so-called jumpers, but for sure the wall would bring problems to them and their bigger companions. The cannon also is a nice addition that would help if the wall can't, but I have to say that the tube doesn't look that well to me. Only my opinion, I think. That said, this MOC is unique and wonderful, I love it. Amazing work, dear, and hope you will come up with more of those machines! =D
