Sometimes a constraint is beautiful both visually and logically, and a skyscraper line fits that perfectly! I plan to make more use of them in the future.
Rules:
- Normal sudoku rules apply.
- Skyscraper Lines - A digit on a diamond indicates the number of visible skyscrapers along its line (not including itself) from that digit's direction of view - digits may repeat along the line if allowed by other rules. Example: If there is a diamond with a value of 4, a legal string could be 2356236, since the first 6 hides everything behind it on the line, including the next 6.
- Dutch Whispers - each digit on an orange Dutch Whisper line must differ in value by at least 4 from its neighbor on the line.
- XV sums - digits separated by a V sum to 5; digits separated by an X sum to 10. No negative constraint.
- Ratio Kropki dots - digits separated by a black Kropki dot have a value ratio of 1:2. No negative constraint.
Solution code: Row 4 digits, left to right

I generally find skyscrapers hard so I left this puzzle for last but this one was fantastic (as usual)!
PS I have now solved all 101 (as of today, at least) of your amazing puzzles! Thank you so much for this marvelous catalog! For background, I started watching CtC earlier this year and thought "these are great to watch, but I'll never be able to solve these myself." I eventually decided to try, and one of the first puzzles I solved was one of yours. I felt amazing! That led me to set a challenge to solve all of your puzzles, which has been so much fun. THANK YOU!
Edited to add: And just like that, you published another puzzle for us to solve! :)

As being said it looked intimidating at first, but once started it was quite approachable

The upper left (or alternatively the lower left) skyscraper line is redundant.

I am usually not a fan of skyscraper clues, but this was fun. Thank you for setting and sharing, NotSoMagnifique!

Lovely!
>>>NSM here - thank you! This one had had a limited response so I didn't know if people were actually enjoying it.
Maybe the skyscraper lines are a bit intimidating. First I looked at them quite a while for a break-in. Once I noticed the actual start (which is wonderful, btw.), the solving had a very nice flow and the skyscapers joined in quite naturally.
