There will be no better quality. This is it, for this game.
I'm not a 3d artist, I just have beginner-expertise, which is barely enough to buy 3d-assets from the assetstore and other platforms and do modifications.
But I tried to improve stuff over 3 years like the shaders, hairstyles and textures and such.
But this is it for this game, and this is how far my skills go.
When I have enough income that I don't need to fear to become homeless anymore, I could hire a real 3d artist, for the next game in my radar.
But looking at the income now, this is something for 2021 or 2022 perhaps.
