f95 may seem scary but i promise it is the best place to get your game to be known by others and get feedback. it would be a bit of effort but well worth it. i know many people have been looking for a futa on female renplay games. so you would get a lot of traction. here in itch its just hard to find stuff they get hidden and even if you buy/play a lot of ero games it still won't recommend you any. About the graphics idk tbh, i was more focused one story and pretty futas. Which i find lovely so far, new characters outside of the family would be nice way to ad vareity in the long run as well. i guess if anything i would say a good game to use for inspiration that works similar to yours (with a femboy) would be My Futa Family, by duckworm you can find it on f95 (btw they dont even have an itchio only f95 and patreon and discord it only took f95 for them to get super popular.)
Thank you so much for a moment of your time, and this game that i have been waiting for quite some time. I am glad you are still working on it even if slowly.
