Fala amigo, Obrigado pelas palavras gentis. I try my best to give some originality to the project, the basic vision is that this is an Adult Game with an actual Adult story, I'm not claiming that my game is better or something like that cause it isnt hehe but I feel like a lot of games on this site are made for 12 year olds.
As for rendering advice. Well for your models to look less like those uncanny valley looking dolls you should try to think a little outside the box. If you use DAZ I recommend using custom morphs made in blender or learn to make them yourself, It's a lot of work but i really think it's worth it. The vanilla morphs and most of the other ones in the store are really just a combination of vanilla ones so that's why those models look so similarly bad IMO. You don't even really need to use DAZ there are other progressive rendering pipelines other than Iray. For instance I work with some 3rd world country affordable hardware so Iray never was really a practical option for me timewise. Instead I use Unity's SRP wich is realtime and has a lot more options to increase performance on shitty hardware and if you know a bit of coding you can easily upgrade it for physics and stuff. It's a bit steeper learning curve than DAZ but i gotta work with what i got. Yes the rendering in DAZ with Iray has much better image quality, but Character Geometry, Scene set up, Post Effects and posing are not necessarily binded with money/hardware quality it's a skill and talent thing. Keep practising and experimenting with different tools and see what works best for you and I'm sure you'll improve
