Personally, I like the artstyle. To me, it looks like someone actually drew it. Love the art styles of other manhwa too, but those to me are just so amazing and detailed and out of reach. This is down to earth and I like it.
the artstyle isn't even that bad, it's pretty considering it's fanart. the only tiny problem is the writing since I'm not used to reading cursive so it's kinda hard to understand
