It is a nice and easy puzzle. Thank you for sharing. If you do make a series then don't worry too much about the difficulty. Try to focus on making the logic interesting and fun to solve. That tends to make better puzzles.
You could try palindrome lines, irregular regions, extra regions, Region Sum (counting) lines
If you swap letters for 0/1 you can also do a lot of other things like Slow Thermos, Little Killer clues or Arrows,
Have fun and keep setting puzzles.

- Changed online solving tool (I didn't know it was possible to input letters on SudokuPad)
- Linked ABBA

Yes for series. Yes for two lines for now. Yes for sudoku-pad link. If you substitute colors for AB, the final grid is soothing and serene. Job very well done.

Nice puzzle! Maybe try introducing a new type of line to make it harder. Thanks for setting and sharing!

Thinking about turning this into a series if enough people like it. However, I'm not sure how difficult they can really get.
