Move 2: This is too conservative. As black with a handicap, you have a substantial advantage early in the game. It declines, of course, as more stones are added.
Right now, with this move, you have a 7 to 1 ratio of stones. In 100 moves, you will have a ratio of 107 to 101 - almost 1 to 1. So to get the most of your extra stones, you must use them early. Attack him with something like M3 or L4.
10: This is way too cramped. Think expansively. O16 is good. P14 might be fun, though it may be thin.
12-16: Good moves. They make use of your otherwise misplaced stone at Q15.
18: Awwww...

...you're thinking too small here. Play Q9, and look at the entire top half of the board.
22: Good! Too many DDKs would play S6.
38: A little over-concentrated. D7 would be fine shape.
54: This leaves a gap that will cost you. Better is D12 or C11. B13 works too, but it could be tricky. ( BTW, when you have a spare move, you can kill his corner with B18 )
68: This is thin. If he didn't have D13 in place, maybe you could do it. Best here is probably F12.
74: You know that E16 can't be allowed to run. That is good. You see the problem, so why bother with half measures in solving it? Fix it permanently with F16.
This leftver problem, BTW, is what we call 'aji'. You have 'bad aji' here. F16 would remove your bad aji.
84: B8.
89: See? He has a ko threat. If you had played F16, he would not have a ko threat.
104: Why fight the ko now? How much is it worth? He can create a second eye any time with C15, so you are not fighting a ko for his life anymore. You are now fighting for a few endgame points. They may be important later, but they are trivial right now.
115: Note that he lost the ko, but is still not dead. Imagine if you had let him win the ko and played a black stone at K15. The whole center of the board starts looking like your territory.
I have to quit now...maybe more later.
