If you ask me straight up, I definitely 100% prefer 3d over AI. With that said, I didn't mind the AI illustrations. If there is one good thing from all this is that hair is smoother. I love the 3d models in general more but hair was a bit of a rough spot for me for those with white or light colored hair like Samira's. AI can look generic after seeing a ton of them online but I admit it grew on me in this game and it can still be hot if the scenario is right tho not as much as before. I do miss the 3d models though and hope it comes back.

For criticism of the game, my pet peeve is that I really missed the slave presentation before they do their oaths. What was nice was the anticipation and suspense on how they'll turn out. The slow shot-by-shot reveal of the slave's new assets, then showing their full body view, and finishing with squatting or posing for their oaths. It was perfection. In this game, revealing their final forms before they make their oaths kinda missed the mark for me tho I still enjoyed it. For a suggestion, if you wanted to show progress for their transformation, make an in-between form of their original and final form, and once they finally surrender, they make their final transformation before making the final reveal and slave oath. My other gripe was the lack of harem sex ending: a threesome with both of their corrupted forms or even a foursome with doctor or Selena would have been welcome. Isis had one after Selena's corruption and Valdana had the mother-daughter pair end. The lack of crotch tattoos and animations were missed, but I hope it's a technical issue after using something new and hope to see it more in the future. 

After saying all that, the game and series in general hits all the right notes for me that very few games or media manage to do having corruption, brainwashing, crotch tattoos, squatting with arms behind their head, lesbian/bisexual play etc... all in one in the way I enjoy it. I actually prefer this over its inspiration because the pacing is better and it presents my kinks in way better imo.
