Well, that is quite a piece of work!)

Nice style, but I imagine that when a cannon shoots from a BLIMP - it must shake the latter quite a bit. Don't get me wrong - I don't insist on any kind of realism, but I just want to see a game someday with blimps shaking from every shot "sent or recieved" )))

Overall - a great proof of concept

I really like your art style! I get that this was just for an assignment (if the assignment was about your understanding of foreground v.s. background, you get an A), so I'm just being super picky when I say that the black blimps movement was a bit choppy, and I think adding sound would make this super awesome
