I think this is an easy skyscraper puzzle :-)
I hope you will enjoy and I would be really grateful for all the comments and ratings.

Normal sudoku rules apply.

Antiking: Identical digits cannot appear in cells a chess king’s move apart.

Dutch whisper: Neighbouring/adjacent digits along an orange line must have a difference of at least 4.

Skyscraper: A clue outside the grid gives the number of skyscrapers visible from that position looking along the row or column, where each digit’s value indicates the height of the skyscraper.
