The problem with a lot of steampunk stuff is that it is far too detailed, too intricate, too busy. This does not have that problem. It doesn't look ruined by "extra" gadgetry. Great job!
Arm-mounted cannons. Well, why not?
oeh a build on shoot thingy! looks awsome!
Fantastic, coupled with some hoses and a gas tank, it would make an awesome wrist flame thrower.
