Reference sheet for Jack.

Yeah, there's a couple different outfits--his Fazbear Security Uniform, him a little dressed up, him in his... boxers... and the last one is the beginning of some crossover art I wanna do.
I've been dicking around with the idea of "Five Nights in Rapture", and that's Jack as a splicer. It's gonna be pretty fun.
The last series is also what I used for character reference for my senior film--I wanted to model Jack anyways, and I figure let's stick him in my film so I have an excuse to work on the model.

Yes, I am a sucker for characters named Jack, and his wrist tattoos are homage to two of my favorites:
The wrist chain tattoos from Jack from Bioshock and the gear tattoo from Handsome Jack from Borderlands.
