Susie's foot puzzle mats

Some kids have those 'orthopedic foot massage mats', often in the form of puzzle pieces with different 'textures' that provide various sensory effects on the soles of their feet. While they're primarily targeted for younger kids (typically under 6 years old), I believe that older kids and even adults would benefit from them as well.

When I first drew this in early 2021, I felt that Susie would enjoy standing on these kind of mats, especially during the winter months.

Note that I had outlined this using GIMP's Paths tool, per my standards for digital art from back then.
