Symmetrical Fan

I hope you will enjoy my first ever created puzzle!
I would be really grateful for all the comments and ratings.

Normal Sudoku rules apply.

Sandwich: Clues outside the grid indicate the sum of the digits "sandwiched" between 1 and 9 in their column.

Kropki: Digits separated by a black dot are in the 1:3 ratio.
Digits separated by a white dot have a difference of 2.
Not all dots are necessarily given.

Arrow (gray): Digits along an arrow sum to the number in the attached circle.

German Whisper line (green): Adjacent digits differ by at least 5.

Dutch Whisper line (orange): Adjacent digits differ by at least 4.

Renban line (purple): Set of consecutive digits in any order.

Parity line (red): Adjacent digits alternate between odd and even.

Thermo line (gray): Digits increase from the bulb to the end.

Between line (gray): Digits on the line are between the values in the circled ends.

Lines never share the same path (i.e., there is no purple or green line under the red line).

nice break in, took me a moment to see it...
still that bad taste in my mouth from an otherwise nice puzzle
so sorry, can't help but adjust the rating accordingly

IDK man.. not a huge fan of puzzles that are essentially a giant swastika once the first numbers are in;
I know I know... easily to get a symmetry like this on a grid pattern, all true..
but maybe one could "try and avoid" these things...
Times are long past since it was a symbol of luck and good fortune (sadly enough)

SK: I am afraid that if you see swastika everywhere then you have some sort of problem. This puzzle has nothing to do and is not even close to look like swastika.

I started at this stick for over an hour. Decided to reread the rules to make sure I wasn’t missing something…wait, numbers outside the grid? How did I miss that entirely????

Very well set puzzle.

A lovely debut! It's the rare sort of puzzle that is on the easy side, but still manages to be engaging and well designed throughout.

Absolutely brilliant puzzle, took me about 43 minutes (with some distractions and a few minutes until I figured out the 2-dots were not black but white). Hard to believe this is your debut at setting.

The 2 stars are probably justified because it's a lot of constraints interacting. Very much looking forward to more creations!

a good, solid puzzle with zero defects - so deserves a 90% rating.
level 2 = which means, very easy for experts, and beginners can do it, with effort.

the clues interact beautifully. it's a lot though - with this many rules missing that a crucial pair was disambiguated adds a lot of time as i go over what can be the next focus before i get back to plain sudoku and resolve the pair. i think with so many rules some clues should be more obviously irrelevant until later, this puzzle felt a bit too densly packed. 60min solve and this level of difficulty i expected 20-40. overall a great debiut
