This is brilliant ^^ Got here after a treacherous journey from Honeybee. Have you ever seen the illustrations for The Edge Chronicles? Basically the Sky is treated as a sea and they use sips rather like yours
^^ They only really start using combustion engines in the third age of flight (First age being flight rocks, second being craft made out of wood lighter than air)Check out the Immortals, the most recent one ^^ Half of the brilliance of the videos like Honey Bee and Captain Albert Alexander is the expressive and robotic movement ^^ I'mma try moving like a robot, but also drawing like this. Inspired!
I see you've been likened to Tim Burton, have you ever seen Clive Barkers paintings? You're style reminds me of him as well... dark and whimsical (sorry if this posts twice I was commenting at work when I shouldn't be...)
I really like your design. I love gritty-off kilter worlds that require an audience to look twice I also love the way you made the sails look like fins, and that the whole thing looks like it's held together with bailing wire
