IGS 7k game for review

I'd love a review of this game I played on IGS (time settings 1 + 10 per 25 moves). I blundered rather poorly in the lower middle. Comments on that fight are quite welcome, but I'm interested in comments on other aspects as well. I've put some questions/comments in the sgf.
Context: At 7k on igs (= 5k kgs supposedly?) I lost my first 3 games but have won my last 8 and this one nearly broke the streak. I've just been promoted to 6k (still provisional, as I've only played 11 games there so far), so we'll see how that goes.

13: you didnt gain any advantage by playing this move. better left alone.
15: N16 is not better. you want influence to drown one white stone on right
21: i will play Q7. if you attack to hard they will simply use them as a aji and tenuki. you want to give him place to run and same time get points.
27: Q6 is a better move i think.
35: i think this move is the best move you can play if you want to play there. but you must understand why this move is the best move.... it takes some reading.(very hard to explain)
45: you must learn to tenuki. ther is no need for you to play this move.
49: i guess you played it because it is a joseki. do not rely on joseki but go with your reading. it will help you improve faster if you learn not to follow joseki. (it is illogical but true many times)
57: H5 is better.
61: i am thinking O2
65: yes..G5
i will stop here.. there are many other moves that i didnt like..but..i think you have enough to study with.

Thank you for the comments.
13: Is it because it weakens the upcoming attack below? Especially given how the game went through white 20 it seemed safer to have a more secure corner, but maybe that's just some life & death weakness on my part?
35: I couldn't read it out entirely, but it seemed this either captured Q10 while forcing white to push from behind or would help me seal white in. Is this basically correct, or is it yet more complicated?
45: Yes, I see. I played it because I expected white to continue (and lo he did), but that's rather a bad habit, and probably white should have played tenuki as well, as his group looks alive even after my 45. Perhaps even if it had been sente against his group I'm supposed to leave it as a ko threat?
49: Yes, this move was silly. Perhaps D3 or, maybe even better, D5 is what I should have played.

Thank you, that's a much better reason to leave black 13 unplayed than I was coming up with.
