There's quite a few I can think of if the art was better more people would probably read it. Art can make a huge difference. Just look at solo leveling and I Got a Cheat Skill in Another World and Became Unrivaled in the Real World. Barebone power fantasy tier writing but fantastic art. I don't think any would be a masterpiece but certainly an improvement. I think transfer student storm bringer would have more views of the art got updated. There's some isekai that would probably do better with improved artwork. Like that berserker mob one. But those are the ones off the top of my head. I'm trying to remember the name of one more involving a girl having to kill giant with her husband but I cannot remember the name
