Help with Estonian Sudoku

Once again, 9 out of 29 sudokus were left unfinished, unsolved or with errors, but 7 out of 8 from the 1st round I have later solved with either minor or major difficulties. Unfortunately, the unfinished one from the 2nd round, or sprint, was lost because I forgot the competition location on my sprint sheet. But there remains 1 classic sudoku, or 70-point, which I can't seem to solve. I have tried different methods, but to no avail. There are quite a few squares with only 2 options, so I could solve it using 50-50 (by experimenting), but I assume that it will still be solved logically, and let's be honest, solving it with 50-50 is still not right. So I'll add a picture of this sudoku, maybe some pro can help me?
PS The grid is not even and is crooked because I didn't have a ruler handy when I drew it, but I hope you understand.

Hmm, can't anyone else do it? 😕

It is solvable. The 70p problem was easier for me than the 55p one. The ones you have now are correct.
