U know like how when an anime series changed studio and the art went downhill?
I think most of the ppl who are salty about the art changes KNOW TOO, that art of promo and actual manga/hua/hwa are of different artist in every manga. There are rare cases when they're both drawn by the same artist. So being salty about it is having double standards and disrespecting author's decision and work too.
I get what u mean but usually the difference in art style is still pretty & easy on the eyes. Not that i'm saying this art style is ugly, every artist has their own style but this does look like a rough sketch rather than normal manhwa?
I think the reason ppl are salty about the art is coz the prologue/the short 1st chapter's art is really beautiful so when the art changed they feel like they're cheated? I guess?
