This project is a UI icon design practice for one of my school assignments, where we had to design several icons for an imaginary game using any style we wanted. I chose to do a gardening-themed mobile game featuring a radish character. 

The assignment brief emphasized making several sets of 3 icons using the same object, but showing a tier-based "upgrade". Without any wording prompts, the user should be able to visually understand where the icons rank in its tiers (i.e. which icon corresponds to a lower tier etc.)
