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.
Although the faces resemble faces, and the "hair" looks like hair, what about the backs of the heads? What about the chins and necks? I wish that Creed had tweaked the Indian heads' outlines so that they more closely resemble heads. This is a common problem in first-timers' tessellations of heads.
