You can find (AI and non-AI) art on Pixiv.
Personally, I post my stuff overs there and then on sadpanda.

Plenty of (AI and non-AI) art of the twins on Pixiv - way more than for LBG. The franchise has always been the more popular one in Japan.

AI art can be intimidating at first but modern tools are incredible.
I have only one week of experience on the subject lol, still plenty of room to improve. Like, I should really upscale my stuff.
