I haven't done a lot of Steampunk work per se - frankly I don't know why it's kind of right up my alley in a lot of ways.
I guess I have always preferred a more bleak sense of science fiction - steampunk at it's heart has always felt more optimistic in a way. I could be wrong. Maybe this is a new genre I could get into - SteamNoir, haha. Or SepiaPunk. UmbreNoir. Ok I'll stop.
