Great stuff. The symmetry option is very useful.
It would be great if you once made a more "advanced" version of this with more user control (color palettes, detail levels, random mutations of a single sprite, that "mass-export" option suggested by GeminiDark...)
This has a lot of potential. u could collaborate with Donitz (creator of procedural tileset generator) and make the ultimate pixel art generator tool and sell it for like 50 bazillion dollars
Also I love the random generated names that I've gotten (like 'salt', 'salty salt', 'cabbage' or 'fermented dave')
