This tessellation shows translational (slide) symmetry.
The "tile" (tile = repeating shape) is very neatly, precisely reproduced and fits with all the other tiles perfectly, without gaps or overlaps. That's what a proper tessellation does.
If I offer any constructive criticism, it's this: I wish the artist had tweaked the outlines so that the feet would look more like feet and less like square empty kleenex boxes on their feet (like Howard Hughes wore). I'd also like to see less white, since white space is often interpreted as "gaps", which are not allowed in tessellations.
