One concept, three aspect ratios: Exciting Planeswalkers.
The goal was to resize the creative for different screen aspect ratios to maximize user experience when viewing on different platforms.
A best practice I established for the wider creative team is to start in 1:1, so when resizing for 16:9 and 9:16 each new aspect ratio only has to be expanded to one direction at a time, either vertically or horizontally. This optimized workflow refined quality control, allowing designer focus for extending in only the one direction rather than both at the same time.
