Interesting. Without looking at the other images you put near the shirt design, the head in the middle looks really strange. The tear and dot make the face confusing. People look for eyes in shapes, it is just something we do. I think you need to remove the dot, the tear and maybe the white shine inside the head in order to let the viewer know that the thing in the middle is a head without eyes and hair. The moth could be simpler too.
Most viewers will not take the time to figure this shirt out.
