My endgame kind of suck now that I think about it

I was initially quite proud about this game, how I used the aji of dead stones to prevent W from cutting me off and then to wreck his area. But then on reviewing it, on top of finding a few place where I missed better sequences, I realized how much big points I let my opponents have (I didn't realize I could get more than 10 points by a cut that had been made possible by the middle game fighting, and let him have most of the big double sente moves)

So apart from pointing out mistakes I made I may not be aware of, I would like to have the endgame reviewed.
