i might say bodies but more human forms and partial faces. also though if i take a step back partof it looks like the heart to me in the center left as well as kind of a close up on a cell or snyapse in the brain sortof abstract. idk i feel like it coulda been drawn with purpose and part of that purpose would be to look like many things. idk i found your box puzzle the other day great i got like 80% through in my head but didnt finish bc of gaming lol
