Erica 9

This time Erica became extreamly challenging, so it is not recommended to everyone.
However, do not worry, I promise to make 10th episode nice and easy.
I hope you will enjoy and I would be really grateful for all the comments and ratings.

Normal sudoku rules apply.

German whisper: Neighbouring/adjacent digits along a green line have a difference of at least 5.

X/V: Digits in cells joined by an X sum to 10. Digits in cells joined by a V sum to 5. Not all Xs and Vs are given.

Entropic: Any sequence of 3 adjacent digits along a peach line must have a low digit (123), a medium digit (456) and a high digit (789).

Entropic Line Explanation:

Basically, if one digit on the line is low, then every third digit will also be low; same applies for the remaining groups.

The Erica Series:
Episodes: 1, 2, 3, 4, 5, 6, 7, 8

Super fun puzzle! The break in had me coloring all over. Almost looked like an abstract painting of Erika at one point.
