I'm happy you like it. Vanilla's clean belts look uncanny to me at this point. I need to add an option to tint the sprites a little to really complete it.
Agreed, it was also a bit worse as the modpack I made uses only a single icon for the new ores so they looked absurdly rigid and uniform. This was a great fix. Would it be hard to add a random rotation as well? Not sure how it would look but maybe, just maybe..
I don't think rotation is possible. There isn't a field for it in the docs. It would probably look a little goofy anyway for things like batteries, barrels, engines, science, etc. Everything with an obviously flat bottom should sit flat on the belts.
