I recently did some drawings for the Walking Dead season 3 sketch cards that will be out I think early next year. Part of my assignment was to draw a series of 'walkers', but I could not use images from the actual show as reference. So I decided to turn friends and family into zombies (including myself). I had this great idea to draw our own 'zombie cagefighter' as a Walking Dead zombie, but after reading the fine print which said no celebrities, I decided not to include him in the set. However, I still thought it would be a cool idea for a sketch card, so here it is, Zombie Cagefighter Nate Quarry: 2.5x3.5" copic markers
Not to be obtuse, but I'm pretty sure such a thing already exists.
Nice painting though. Maybe do a series of zombie fighters doing zombie MMA? I wonder if Zombie Rousey can still armbar Zombie Tate when she has no more ligaments to bend. Or if Zombie Anderson Silva can still do matrix moves at zombie speed.
