In 2016, I worked on Zootopia Crime files, a mobile 'crime investigation' game based on the Disney movie.
Here's parts of the creation process for some of the levels, from base environment illustration to fully-integrated object-picking stages.
Assistant Mayor's Office
Clawhauser's Desk
Object Integration A: Empty Background Illustration
*This exact background was NOT by me - only the integration. On Zootopia Crime Files, we integrated objects on each-other's background illustrations to get a more homogeneous result across the game.
Object Integration B: Laying out 50 objects (stock photographs)
Object Integration C: Rendering the object in the game's style
Object Integration D: Creating covers (layers) for partial hiding (this image contains around 100 separate assets)
