Even the current adult Changedlings don’t seem to have any gender differences. They all seem to have the same general snout shape and are around the same size and even their eyes have fairly similar designs too. Occellus is currently the only one that seems to have different shaped eyes and eyelashes from my recollection.
Love that this Thorax evolution still looks like Thorax (i. e. not just some random maniac with a sharp-toothed grin). Facial expression fits perfectly.
