I think itīs the exact opposite. While manga is an important part of the art form comic book, these Vallejo paintings (and many others in the style) are representative of pulp trash; the kind of "art" used for the covers of cheap fantasy novels.
I may be biased being more of a comic artist myself, but generally I see the Vallejo style as very low-quality art. I am glad this kind of artwork has since almost disappeared from video game covers at least. Each to his own though.
