This is a very lovely puzzle. The negative constraint works wonderfully, especially at unexpected places. Thank you for setting and sharing this beautiful sudoku :)

Really nice!! Found it very challenging at times, having to look in unexpected places, but the 'lightbulb' moment was so satisfying every time. Thanks!

Had to keep reminding myself not to apply the negative restraint inside the fog. Fun puzzle. Thanks!

The negative constraint is surprisingly powerful. A few times I was wondering why the fog had decided to clear from a useless place, only to be proved a fool. Great puzzle, thanks.
