As someone who mostly uses textures for contrast/coloring, I'm in awe. The way you use textures for composition and play around with them is absolutely mindblowing! I can't even remember the last time I used a texture on Exclusion! xD

BUUUUUT please give the pen tool another try! I promise, it's absolutely worth the effort! I swear! Do it!!!!!

I'm also very envious of your texture randomizer, which language did you use to code it? Please don't say JS! (I swear I'm going to learn how to code in JS properly one day, but today is not that day xD)
Do you think it would be doable to code it in Python? I worked with Python for a project and it wasn't that hard to handle folders and files.
