Here is a sample of my work from Bioshock Infinite. I think the total amount of characters within the game is around 60, divided between 2 character artists and some outsourced work. So - it would have taken forever to prepare all of the pieces and would have been a bit overwhelming. I took on the role of Lead Character Artist during development and, other than the responsibilities that comes with that title, mainly focused on combat characters and general population.
Thanks for looking!
