I'd only cosplayed one thing, and I wanted something that everyone recognized but nobody does. Kurotsuchi hit me like a ton of bricks. Coincidentally, as I watched episodes for reference material, I began to like him, wheras before I didn't really care for him.
My Favorite Aspect:
His extending arm, I made it as a spur of the moment item but it turned out so great, if only I could get the hanger wires to stay on.
Least Favorite Part:
The mask, as much as I love it its incredibly annoying to wear, I can't wear my glasses and I don't have contacts, not to mention that I can't breath through the mouth and I had to affix straws to the inside of the nose so I wouldn't breath into the mask and suffocate myself.
Easiest Part:
His Detonator, it came out perfect and it only took about 10 minutes
Hardest Part:
His Shikai Ashisogi Jizo. It was my first attempt at fiberglass and resin and it came out really bumpy and even spikey in places, so much that I couldnt sand em down properly so I coevered in duct tape(for traction) and then tissuepaper/woodglued it all then spraypainted.
