I feel western porn comics have a tendency to have a rough style, but that's mostly true for what I got published here in France(and not counting french manga)
For instance, stuff like this:
then there's stuff like this, this is a bit better but can disgust non-manga fans
It seems to be very niche, finding a book like those can get hard at times.
And then there are the independant authors and we got a pletora of people.
It's the same deal though and you can have a lot of different styles.
Doxy and gy are two authors I can remember who I can read anytime.
Funnily, I've known Doxy for his works belonging to the furry fandom in the first place, and I have to say, there are quite a lot of talented people in this fandom, though only a few does actual comics.
So far, I've got no western porn comics in my hands, though I kinda want to get a book in particular (but I'll have to import it and it triples the price, so I'm waiting.)
