Thank you
Unfortunatly, I only have a few pictures of the building process, but I'm working on a second suit

(Actually, a third) I will take pictures.
Soul Samurai, the rocky base is the battery holder. Is a button battery of 3v. No switch, you put the battery and the light turn on.
I had to made a hole on the base so the holder wouldn't elevate the miniature too much, I glued it with superglue (glue for miniatures doesn't work) and some green stuff for the big holes.
It doesn't have a switch, just put the battery and the light goes on. I could have use an "eker switch" but meh, it was easier to just take off the battery xD
