Alas I've never read the books. But the game makes her flawlessly beautiful and makes sure to show off her nudity (not Geralt's lol). I mean I'm straight I just dislike dishonestly represented sexuality.
Why is Dethmold so fuckin' ugly, then? Idk...I think it's part of the immaturity of some parts of fantasy. It's ridiculous. Especially the Phillipa Eilhart scene...that was essentially porn put in the game. It did not need to be put in. I say this cause I was a long time porn user and it was really negatively affecting my life and relationship with women. I quit it and now have a girlfriend and am much happier. But being thrown that scene in my face was just aggravating, like if someone forced drugs on me. The scene with Geralt and Triss was a lot more vanilla, if I bit too picturesque. And I (Geralt) was a sweetheart to her right before. So it reminded me of me and girlfriend, haha.
If you, again, read books of Witcher, you will know that all that porn is a part of Sapkowski style. All dirty things and scenes are represented there almost in every tale of Geralt. It's necessary to be put in the game so it will be authentic to the original books. When I played the game series, yes, I find that all a bit disturbing, but seeing them I could say yes, that's a true Witcher tale ^^
As for Dethmold, he is an anti-hero, and must be represented in a proper way. Such bastard like him can't be very cute and handsome.
Idk...Game of Thrones books are explicit but are rarely meant to be erotic, I think. Which is one reason people complain about the show. But it's a bit more progressed than the Witcher as far as being on equal grounds and not feeling like it's geared toward straight men only. They could have made the scene between Phillipa and Cynthia more normal sex in bed than freaking bondage, I mean come-on? That was a redflag for me. But however you view it, I suppose. My own fantasy I write will have sex but as I'm avoidant of porn I will try to keep it more honest and make it tell a story.
And Jaime Lannister is handsome but is also douchey (to an extent).
For me GoT books were as erotic and as exrlicit as Witcher. I haven't watched the TV series, but that doesn't mean much. The devs could make much this much that, but they did as they wanted. And they wanted to show not only pure sex with everyone, hey. That bangage and slapping just underline Philippa's spoiled character and the hero doesn't trust her that much.
The only thing I would like to advise is to keep an attention to the anathomy. Her right arm is a little bit too skinny (looks like she had only bones and no flesh on it), and palm to small. But apart from that detail, it's a nice work, you've captured Triss very well
