Exchange sac the queen? What would you have done?

Just wondered what anyone thought about my decision to exchange sac my queen in this game at move 33 in the below. I was already a piece up, and so by the exchange I would have a bishop, knight and rook for my queen, which is pretty nice compensation. Would others have taken the same route, or played Kf8? I couldn't see any way for me to get checkmated, and so I think Kf8 was at least safe, and the possibility of Nh4 looked very tempting, but it would have left a much more complicated position, and I wasn't confident in my calculations. Does anything think 33 ...Kf8 followed by 34 ...Nh4 would have been a better way to continue?
