Odd-Even-Big-Small Sudoku (Fun With Sudoku #169)

This is the first time I am posting Odd-Even-Big-Small Sudoku. This Sudoku is part of World Sudoku Championship 2015 and I tried to create this Sudoku for the practice before this championship. However, I failed to create this Sudoku that time and left it in-between uncompleted. Last week I tried again to create this Sudoku and it took me a lot of tweaking to create this Sudoku correctly. There is a lot of learning I got while creating this Sudoku. Also, there is a lot of feedback I got regarding this Sudoku after the testing of this Sudoku from Prasanna. I will implement this feedback in my future Sudoku and Puzzle creations to improve upon my Sudoku and Puzzle creating skills. Anyway this Odd-Even-Big-Small Sudoku, I am posting in Fun With Sudoku Series as the 169th puzzle in this series. Can you solve this hard Sudoku puzzle?
