I believe it is responsability of the Studio to do a background check of the artists you are associating with, from soliciting In-Real-Time video process, checking their portfolio and identify a stable evolution of the work and consistency in quality of lines, technique, style and similar, unless you're actually enabling that behavior and just going with the flow for as long not many find out. Besides supervising them be it through Discord Calls or Google Meetings by having the artist share their screen, that also helps register the amount of hours they are working.
Besides, having an Art Leader within the branches you are managing, that is experienced enough to identify fraudulent artworks to not damage the image of your Studio and can reject unqualified artists beforehand.
I remember firmly that you have already made a Topic offering illustration services back in 2022 and your post was removed for violating the Forum's guidelines, not only regarding the tracing but soliciting sales.
Not to mention that so far, everything that has been shared seems to be of only one guy, which is Mario Creations,
Copied design
Original
Fake Process
Actual comparison between traced and Original
This one too its pretty evident, it looks like a collage of images that were cropped then traced over. The sketch follow the same pattern of the Fake process of the Solo Leveling traced illustration.
Besides, the more I glance at this image the more messy it gets, quality increases and decreased depending on each drawn object, details too lack consistency and even looks as if each image has a different coloring and shading technique.
And its clearly that the cover for the Jsunz album has elements traced from Lookism
At this point I would suggest completely removing whoever is involved with the Studio, and its concerning that there isn't a section with all artists involved, or who has been in charge of which illustration. And the fact that the Jzun illustrations have been commissioned work, its quite alarming.
