Anytime the head/face looks weird relative to the body, I'm gonna say there's a pretty good chance it's traced. The general lack of coherence between pages and plot outside of "haha sex time" probably means it's either traced or heavily borrows from comics by other artists. I don't want anyone to feel bad for enjoying these works since porn is porn. I just want to point out that for an artist with a Patreon the quality is a little more than just sus.
