Hello! The solving took me more than 4 hours. I tried all kinds of ideas, but I couldn't find anything. But I didn't want to give up. When I found the key ideas, it was amazing. I don't think it's a 3-star difficulty. I vote for 4.
I make sudoku too. But I've never been able to do such complex and beautiful things. How long have you been working on this Sudoku?
Thank you for sharing.
MSDOS: Thanks for the comment! I'm glad you stuck with it and didn't give up! I've been setting for a little over a year now. To be honest, I often set first for beauty/symmetry, and then I discover that there is an interesting property or restriction that I can try to leverage.

It took me 2h. The break in was very hard for me but I think I finally found the intended path. Very elegant setting, and rewarding to solve, thank you!
