As much as I would love for Hyao use the edits, I'm not sure he would be comfortable with it. It's not really my art, I just did a silly little edit and drew the lower jaw. Hyao is welcome to use them without asking since they belong to him, I just hope Zoroj is okay with it since it's his art. I know stuff like this can be frowned upon, that's why I just post it here if anyone wants to mod him in. I would rather stay away from drama if Hyao or Zoroj are not okay with my edits. I did this out of fun and love for the game, hope they don't take offense to it.
That's why I only suggested you "talk" to Hyao about it.
No matter what nuance / drama / or credit issues are there,
Those edits are actually good for the game and the audiences - especially considering LD's specially situation. Not just simple Fan arts that exist parallel to the game itself.
I'm also not talking about "should you get credit for it"(you should tho), rather a solution for LD.
And if Hyao Commissioned ZoroJ for those arts, Hyao should have the agency to edit them to better suit the game, if need arises.
TBH I don't think artists / creator will be mad when their arts get "fan edits".
But you do as you please.
