It's closer to old manga from the 60s and 70s. I always hated the term "manga style" because it completely disregards the works of artists like Amano Yoshitaka, Ito Junji, and many shoujo and yaoi mangaka, Japanese artists not known for their "manga style". Hell, even Tezuka Osamu, the father of modern manga, wouldn't be considered manga style by a lot of manga readers or professed "otaku" these days.
