Even though I'm not into shit eating, what bugs me more about this artist's work is the same small, knobbly turd he draws almost every time. It doesn't matter if the girl looks like she's holding in a big load and desperate. This artist literally thinks girls can't hold in a tiny, hard turd for more than 5 minutes. Look at the elevator doujin if you don't believe me. He has changed the shit only a couple times throughout his works, but even those times it doesn't look good.
The overall quality of the art is subpar as is, but where it matters most makes it much worse.
While I have to agree it's pretty weak drawing style, I really enjoy the fact that you state you don't like coprophagia, but admit to reading other works of this author, anon.
