OK I'm just going to leave technical commentary. First of all congrats on your release, but if you want a good AI product you should really pick up some PS skills and learn control nets and inpainting (I'm going to have comments on where these tools could be useful or were misused below).
This is also all just from the post, I haven't had time to play to actually play the game yet.
In the BJ images she has no earrings, then earrings, then a stud in the left ear. This is very easy to fix with PS if you know what you're doing (some fixes are much harder, but this is such a small area to fix). Alternatively if you don't know how to PS it out, then what you can do is use controlnets to do so (you could also try inpainting, but for something like that you'd usually be better off using depth control net at about 0.2 with img2img after drawing over the area with the correct colors).
In the scene at the park there's several issues, first of all the cutouts are sloppy, I'm not sure what method you used but there's definitely cleaner methods available both through PS and other programs. But also
the right hand of the guy is a bit of a mess, and this is honestly probably not worth even fixing for such a simple render, I would have just re-rendered until I got a fix, but you could have used controlnets or inpaint in this particular instance.
Next image in the living room, the cutouts are again a huge issue.
you can actually see the original background behind his hand, which is awkward, whatever cutout method you're using as least make sure to erase any strays from the old image off the layer.
Final image
Again another hand issue,here any of the 3 methods I mentioned could have worked, that hand is definitely photoshoppable with decent skills, and if not inpaint or controlnets both could have done the job, just again prepainting the lines and either running an inpaint on the hand or doing prepainting and just rerendering the image with depth at low denoise until you get the desired hand.
I'm not sure what setup you're running, whether you use comfy or forge or a1111 or even an online site. But assuming you are doing it locally I highly recommend inpaint and controlnet setups. If you use comfy I can pass you an inpaint setup, if you use Forge I can show you how to use both inpaint and controlnet functions in brief.
Also, are you running addetail and upscaling? Because some of the images/eyes look like they lack sharpness.
Anyway, good luck man.
