i think the trend extends back even further to my badlands series. im able to isolate a few of my preoccupations with stitches, flesh and living corpses to my grandpa who i was very close to. he had open heart surgery before i was born and when i was really little i used to ask to see his scars, it made him seem like a Frankenstein, or a zombie and i thought it was extremely interesting and would often visualize how the doctors opened his chest and what all the insides would look like. he also had skin tags on his neck that i used to play with when i would ride on his shoulders, he was probably the foundation to a lot of the reoccurring themes in my work. he died when i was 9.
blood, violence and gore comes 100% from my catholic upbringing. drinking the blood and eating the flesh of our mutilated god.. really made an impact.
i dunno about the puke and poop.. bodily fluids are interesting i guess. maybe more so because of how familiar we are with them yet how gross and odd they appear to most.
im positive these themes will continue, but im not totally sure how. ive noticed my more recent unpublished work taking a theme of the animalistic nature of humans and society.. but i dont know apparent those themes will be to people who arent me.
