Wow what a beauty. Made my day, thanks for sharing. At first I was banging my head and thinking that how on earth this can be a two star puzzle. When in trouble read the rules and realized that there was also a nonconsecutive rule...

Lovely break-in with the top three boxes. Enjoyed some unusual deductions throughout!!

I was very proud of myself for discovering the break in. It took me a good 30 minutes to noodle that out. Once I got the top 3 boxes filled in, I began making traction and finished pretty reasonably. Thanks for the puzzle!

Surprisingly smooth given the minimalism of the grid! Impressive setting
