I've been working on the Power Rangers: Mighty Force at Mighty Kingdom in partnership with East Side Games and Hasbro. Some of the work I did included illustrating game ready characters using designs from the various tv series. These were done to a specific art style to suit our Spine rigging requirements and allow us to continue making content for live service with limited resources.
These were all made using Photoshop vectors to keep the lines as crisp as possible at a lower res.
