That is pretty cool stuff. I prefer the Boba Fett from his Re-visions Star Wars. The eye-holes on his helmet in the Steampunk version are too far apart. Unless he's got eyes like a fish under there, he'd have trouble seeing straight ahead (though his peripheral vision would be just fine ).
I loved his Vader in both incarnations, and the WW II Star Wars figs were sweet. Gaslight Justice League was cool too.
