Harakiri Sudoku X

For die hard fans of big Sudoku puzzles, here is another one – Sudoku Harakiri X!

Basically, it’s a double-Samurai Sudoku puzzle: 8 classic sub-puzzles, which of course don’t have their own (unique) solutions but all together constitute a puzzle with a single solution. This time, however, you must also pay attention to diagonals: ALL diagonals in the puzzle must contain all numbers from 1 to 9. The diagonals are marked in the puzzle so you wouldn’t forget them.

Thoughts and comments are most appreciated (as always)!
