Been wondering (& procrastinating) on this for a few months.
Wondering about if there should be tags when a new work (by artist-B) is inspired (all or in part) by another artist's style (artist-A):
such as inspired_by_gustav_klimt
( I was considering tags such as in_style_of_gustav_klimt but some of the artworks are of MIX of Klimt style AND other style)
Tag that i think is related: style_emulation (but is a mix of other style emulation)
Example A: New artwork inspired by style of Gustav_Klimt
2 examples of A: post #5510953 and post #3582184
(both tagged with gustav_klimt (tag CATEGORY artist), but were NOT created by Klimt ... as far as i can tell)
One piece tagged with gustav_klimt is by Klimt:
post #3071749

Example B: New artwork inspired by style of (Piet) Mondrian
Examples of B: post #707063
(tagged with piet_mondrian (tag CATEGORY artist), but were NOT created by Mondrian)
***
Example C: New artist related to Keith Haring style
keith_haring (tag category COPYRIGHT)
Which is a mix of
i) very close to Haring's style
example: post #3529793 (the art on the shirt)
ii) NOT exactly Haring style
