Ok, lemme take a glance at this one- this is a good level for me to try and review. I'm only a couple stones stronger (just played my first live tournament, rated 7k), so obviously take any suggestions with a grain of salt.
45: E3- I dunno if you can jump out like this- after D3 D2, white can try E2. If black plays F2, then C2 and B2 kills- it's gote and black gets some thickness on the side, so maybe that's not so bad- but it's worth considering.
53-57: this sequence seems bad for you- you shouldn't play so heavy when you are trying to invade/reduce. I think if he had played around F6 instead of b8 you would have gotten into trouble. Maybe start out with something like F5 if you want to play in the area.
It gets complicated after that- offhand, I don't see any terribly obvious mistakes.
169: I think you should just connect with N3 here. You are ahead and you will be able to increase your territory in the lower right by attacking white's weak group. No need to complicate things. I think white might be able to play J3 and kill instead of M5 on move 174.
179: do you need to respond here? Even if he were able to kill your corner with one more move (which I'm not sure about, offhand), your attack on his group in the lower right is bigger- I'm certain you'd be able to kill him with 2 moves in a row here.
~206: Somewhere around here you should look at M8- you can reduce his eyespace in sente.
216: If white plays N11 or M10 here or on the next move, you are in trouble.
Ok, that's good for now. Lots of good fighting in this game- you can certainly be happy with your play here.
