I'm not sure if anyone here has seen the anime 'Last Exile', but it is a show that contains airships and I have tried to recreate the main ship in the series, the Silvana.
She's not perfect, but compared to my other ships (See post: Early Ship Designs, Same forum) she's OP af. I've pitted her against each and all of them in some combination and if she hasn't tied with them she has burned them to the ground, so either poor designing on my part or it's just a good ship.
If you have--or even if you haven't--seen the show, or even if you just have some input, let me know what you think of it and what you would add or do different. I can't make it 100% because broadside cannons like the "real" Silvana has aren't available in game, but I've been having a blast (literally) with it!
I haven't seen Last Exile, but it's worth watching for Airships game ideas/inspiration perhaps?
I thoroughly enjoyed it. It focuses a little more on what are called vanships (basically small aircraft), but there's still plenty of large airship action in some of the episodes that I'm sure you'd enjoy/be inspired by.

I'm not very good at this markdown syntax and I kept getting a 404 error on the embedded video but just copypasta the link without the space after https:
It's subbed in English but the dubbed ones I saw were only 240p which is just dreadful.
Even their power source (claudia) looks like the suspendium crystals in your design.
