this design is still inadequate :/
great comment from ~probabilitydiver
The main questions I ask about this scene are:
1) Where are the supplies, like water and ammunition for the humans, being carried?
2) If these people get attacked, they're likely to be attacked by something very large. A design like this wouldn't really be reasonable if the carriage itself would be intended to fight things that were short, like mere men. The men at the top probably shoot at them. The carriage is likely to remain erect when it fights things worthy of engagement, since if it bends over, it throws the men out of the top. Maybe you can show some sort of weapon that the carriage itself would use? Something it might carry, or claws on its hands?
~Feedback is appreciated~
