I like the direction your ideas are going. I am enjoying this sudden splurge of steampunk and industrial units that has hit the scene lately.
Only real complaint I have is the aesthetics choice of metal for the gun, would love to see perhaps a retouch or an update with an alternate.
I am assuming it was done as a sort of bronze variant?
Would love to see it look a bit more iron with some thickness around the safety/weight bars.
Outside of that, keep up the good work. Can't wait to see what else you come up with.
