Resign. I'm pretty sure you have a mate-in-two.
The game ends with either of these:
74.Q(9,3)+...K(8,5)
75.B(10,7)#
74.Q(9,3)+...K(6,4)
75.Q(7,3)#
Except for 3.C(8,3)...Bx(8,3) I think you played an accurate game.
My error was 27...R(10,2).
Congratulations - very well played game.😄
Thank you! 
Yes, I did something really stupid at the beginning of the game haha It was fun, cheers!
