With the evolution of sites like DeviantART and how easy it is to find a piece and profit from it, artists who do legitimate work feel more pressured and sensitive than ever due to the issue. Whether you trace, copy from sight (which seems like Shen's case, according to her), or flat out use someone else's design for reference with their consent, there's a phrase that can save your ass.

"Credit where credit is due."

If you're art even resembles vaguely another popular artist's, you can be sure SOMEONE will notice at some point. It's great that people get inspired by other people, but in the overlays provided, you're walking a very fine line of doubt in most peoples' minds. Even by saying, "I applied ______'s style to FFXIV characters!" people would be super mega accepting about the issue, because in modern times, finding originality is something is important, and claiming originality is even harder. lol look at all the patent lawsuits going on now XD
