Sudoku 18: All Odd or Even Sudoku

The last fortnight has been quite packed for me. I couldn't create any sudoku for today beforehand. So got late in posting today :(

Rules: Classic Sudoku rules apply. Additionally, the shaded cells in each 3x3 box will be either all odd or all even.

Sudoku 17: Killer Sudoku

I wish you all a very happy new year. Hope you all have a great year and life ahead.
As the year 2019 is beginning today, I'm posting a Killer Sudoku with the Theme 20-19. 
Though I had created this sudoku before the IB was published, Killer Sudoku is also a part of the upcoming Sudoku GP. I hope this serves as a good practice.

Rules: Classic Sudoku rules apply. Additionally, the sum of digits in cells inside every cage must equal the total given for the cage at the upper left cell. Digits do not repeat inside a cage.
