Very nice! Looks like exactly the kind of puzzle that the 5th year anniversary competition asked for, with its antisymmetrical clues adding up to fives.
Yeah, it was made in the spirit of the competition. Not an official entry being a judge. It came out a bit larger than I planned. I like the center bit, so had to expand the puzzle to make it unique and keep the sum of 5 antisymmetry.
Another puzzle I made earlier in the spirit of the competition was #2615.
