Yep, the door thing was already reported to me, I'll have to redo the render.
For the other mistakes you point out, I'll take into account what needs to be.
Please, use spoilers to hide pictures like this for others.
If I can understand the disappointment, I'm not agreeing on the mature relationship statement, as I put the scene, they both let loose and get into the excitement of the action, and then talked like adults about it, putting a clear line between sexual behavior during their sexual intercourse and the respect they can have to one another out of the sexual intercourse.
This was what I wanted to explore, the fact that Cleavon is intelligent and cultured man, yet he's also able to have a darker side and intense sexual desires, more so than his demeanor could let people suppose (as your own observation shows), and that's what I wanted. And contrary to some other character who enjoy being rough with Myriam and humiliating her, Cleavon do keep respecting her after their sexual intercourse, he's making a difference between their behavior during and out of sex.
The only problem in this scene as it was pointed out, it's that it's again a black character using the interracial kink (though being fair, Myriam start it, which is what I wanted, that at first he is mild then when he hears her, a switch flip), and that's something I didn't pay attention before now.
But in the end it's just a kink as any other, you like it, or you don't, and as others in the game, you can avoid it if you want.
