I could be faster, but there´s an ambiguity in left upper part. However, it´s a very nice hanjie :)

You have to realize that the top left hanjie is perfectly left-right symmetrical, and (other than that one missing dot) up-down symmetrical, and symmetrical across the diagonals too. There's only one possible placement of the last 8 dots that satisfies that.

Very nice puzzle! Thank you!

Two ways to solve the "Winter" season (top left corner) but other than that it was completely logical. The last 8 or so squares are fairly easy to figure out once the rest of the puzzle is completed. Thanks for the fun! ~:)

Nice puzzle, thanks!

The top left corner represents a snowflake. In the alternate configuration it does not much look like one. Nice puzzle:)

Thanks.
