I made 1B pixel art for the first time and I had a lot of fun doing it. Generally the majority of my fxHash drawings were PFPs, which I wanted to change it as well. You can also use Castles as phone backgrounds. Oh also there is no rarity in it, every drawing has same weight.

For screen shot, open it Castles in new tab via fxHash button. And press("S") to take (1152x2048) screen shot.
