You should clearly mention these renders are from the original game, otherwise it can be confusing. Besides you might get prosecuted by Lust and Passion for "unwarranted use of his personal property for Likes on a pirate forum", he seems pretty touchy and is known to use lots of exclamation marks in his legal warnings
!
lol f*ck him and his warnings. He uses unapproved IP and assets in his game on top of the fact the fact that he has no real recourse. International courts won't recognize his BS claims even if he pursued them. The worst he can do is maybe get a Patreon taken down but even then they'd possibly only side with him due to bringing in more business for them than some random making a couple bucks off their fan art.
But do you think Pink Floyd and Rockstar Games gave their permission for L&P to use their logo, names and likenesses in his stupid ass porn game?! No, of course not. He ILLEGALLY put them in there.
Fan art only helps your cause. It's free advertising but he's too stupid and too much of a greedy sc*m artist to see that.
I say make what you want, post it on any one of the anonymous hosting sites that won't give a rat's dick about his crying and enjoy. But mayhe that's just me?
I'd have a much more respectful approach towards his work if he had one toward his fans. He doesn't. Tons of other titles where I'd ask permission to make fan art/side stories of them JUST OUT OF RESPECT (even if I didn't have to legally) becajse they are cool about it. L&P? No. F*ck him and his constant cries about suing people. I say make what you want and let him cry. If that's enough to get him to stop ripping people off, he never cared about anything but ripping people off to begin with.
