Hey, What's Up?

I am happy to share with you a little Heyawake puzzle that turned out to be too hard for SA series, but I quite like it! :-)
I hope you will enjoy and I would be really grateful for all the comments and ratings.

Irregular 6×6 Sudoku rules apply: Place the digits 1-6 exactly once in every row, column, and bold-outlined region.

Heyawake: Shade some cells so that no two shaded cells are orthogonally adjacent and the remaining unshaded cells form one orthogonally connected area. There cannot be a horizontal or vertical line of unshaded cells that goes through 2 or more region borders.

Circles: Digit in a circle indicates the number of the shaded cells in its region.

Squares: Digit in a square indicates the number of the unshaded cells in the 3x3 area centered on that square.
