It's a bit surreal going through this guy's work, because there's like four pages of relatively normal stuff, and then the tits start getting bigger... and bigger... and bigger...
I call it negative artist evolution, where an artist who once had a nice and very varied amount of subjects makes a lewd drawing once and over time becomes all they do for engagement. Sometimes it's something the artist legitimately enjoys and more power to them for that, but I can't help but feel saddened going through some artists galleries on Danboori and seeing it happen across a timeline so to speak.
