This tessellation shows translational (slide) symmetry.
The "tile" (tile = repeating shape) is very neatly, precisely reproduced and fits with all the other tiles perfectly, almost without gaps or overlaps. (The antennae overlap the butterflies above them.) That's what a proper tessellation does.
OK, so it's a good tessellation already. Courtney, now make it a greater tessellation by tweaking that butterfly shape. Make it more like a butterfly. Find a way to make the antennae fit, so they don't overlap the butterflies above them! (Overlapping is a "no-no" in tessellation.)
