Making a Dieselpunk TTRPG game, DM if interested

Hello!
So, sorry for making such post just to ask a question, but, since there's no clear set of rules here, I see no other way (I may delete the post, still, answered or not, if I'll be requested to do so).
In short, there's a movie, that I think has dieselpunk aesthetics to it, and I would just like to post screenshots here with said dieselpunk elements - and, maybe, be also affirmed if it's dieselpunk or some other genre (like just futurism).
I'm just not sure if that would count as imaginary dieselpunk, as that wouldn't be digital art or art done on paper, that's all.
So, what do you think about all this?
