Finished with everything but my military portion (and my history but that's for other reasons).
It's a bit funny since I have tons of ideas how to shape them.
This is my standard infantry, for example:

I also plan to have 6-legged spider like walkers on thin legs which work because Aetherite reduces their weight.
Or maybe make "hover tanks" on Aetherite to pass through trenches without resistance. Basically an overloaded compact airship.
Another of my ideas is to use steam cannons for my mechanical units. Rather than gunpowder they use the pressure of steam to shoot with. Such weapons were actually developed during the American Civil War, albeit not that popular.
