Gaelic Knot

Every puzzle I have posted so far has been an attempt at making inventive new variants. This is just a partial killer-little killer puzzle.

-Ordinary sudoku rules apply

-Partial killer rules apply (digits in cages cannot repeat and must sum to the total given by the cage)

-Little Killer rules apply (digits outside the grid indicate the sum of the digits along the marked diagonal. Digits may repeat).

Here is the puzzle. Enjoy! :)
