1-11 seems reasonably normal. 6 tempting to extend on left somewhere and 10 a little flat, try R6 maybe.
12-18 seems fine, 18 too defensive

so huge
I think

is good - black is much weaker than white, when W has q14 to get shape
:w26:at Q14 seems natural to me

:w34: disaster for white - W is still quite strong here compared to B, using this sort of shape is only for emergencies when close to death, and

could be at P17
instead attach at Q14 (and hope to get P17 in to keep attacking, or comfortably go out to the centre)

can be useful to defend against O15 aji
:w42:seems good to me - locally good shape, B not yet alive
:b43:ambitious making another group ...

maybe should be at D11 first encouraging B to attach to your stones and make both sides stronger. Not to try get a wall (B's top group hard to attack as it can live underneath, and W's right not quite alive), but squeeze B a little, and then go to your 2 space extension

a bit risky to let W take D14 in sente ...

interesting. I think it should be much deeper to reduce B (Q10 normal, or even invasion if you feel Q10 is insufficient). This won't make any territory for W, is a bit weak (far from W's stones), and doesn't impact B much
:b55,57: good punishment. W is in serious trouble now

a bit soft, why not O5 ...
B can't ignore the hane (62) for long, and O14 is always a weakness if you don't protect

best chance to win the game. Not easy for B. Maybe time to sacrifice with H3, O5, J2. Top left corner still has aji
Up to

W still in trouble
Nice try in lower left. At

maybe there was something with D1, A4, B1
B plays very solidly
:w118:. If you can't block on the second line, E14 should be at D14. it still aims at cutting points
:w140: small, black can still hane A7 for ahi
Your ouches around move 200 is inevitable when 2 groups are separated by a black stick ...
