Comic artist only, huh? Alright to save some space I wont mention anybody who already been brought up
Let's start with:Jm Ken Niimura
I love the way this dude puts together scenes and action, and man, that art is to die for, those inks, that design! Crisp.Kohei Horikoshi
of My Hero Academia fame, this guy is my dude! Great energy, great expressions, and i got a
particular love for the way he draws teeth!NAKAYAMA Atsushi
This guy, where do I even start? This guy has some of the weirdest stuff I've ever seen, like some strange mash up between Imashi and Jhonen Vasquez, but man is it INTENSE. This guys willingness to break his characters features and anatomy to get a feeling across is something I admire the hell out of!
There's a bunch more but, they've either been mentioned, or are not comic artists so I leave it at that!
