Glad you're enjoying it!
I used AI, this page is tagged with AI as well as I don't intend to mislead anyone.
That said, I spend a significant amount of time making everything custom, a ton of time in photoshop fixing things up myself and trying to get a high quality end-result. People in my discord have pointed out issues with textures, which I then go and manually fix.
It won't be for everyone which is totally fine, that's why I'm tagging it clearly everywhere it's uploaded. Have a great day!
