I liked this puzzle a lot, though I had to use uniquness several times along the way.

Thanks. Like the opening on the left, just took a while to fit the rest to avoid opening it somewhere else and get it unique.
I always think it's a danger with harder puzzles that it's easier to resort to uniqueness eliminations. Not necessary for the design, but I can see some points where they would be helpful.
