Almost scared me for a sec there lol
Yep your drawing looks way better with nipple XD
From my experience doesn't seem like it is as Tapas featured me when they used to have the Magma Artboard Collabs and my oc was nipple-ing front and center. Posted many shirtless guys from the comic on Tapas discord without issue.
Guess those guys weren't in sexual pose either but, maybe if its in a sexual nature can use the M rating?
Had a naughtier themed image in one episode but I just put M rating on it (an image, foreshadowing an upcoming character, he appears on the cover of what's implied to be a naughty mag).
Going for video game themed look so wld be creepy seeing shirtless nippleless guys
Have a few guys in mesh shirts too so that wld be hard to cover if that ever became a rule lol
