Can't seem to win... please review

Played without komi, so the game was not very close... I'm not sure what my biggest problem is in my game. Please review.

Top of the head comments.

Probably better to stand at O-04.

Maybe a high double approach at D-06.

Wrong side. C-04.

Better at G-16, because of White's push and cut, starting with G-16. Then Black cannot afford to block at H-16.

Wrong side. R-16.

Probably better at D-06 or C-14.

Locally, the keima at O-09 looks better.

interesting idea.

Maybe too early to talk about the game losing move, but this is too small. Think big. Attack big. L-12 is a standout.

Think big. Attack big. K-10. This play also bolsters the G-10 stone and reduces White's potential in the center.

Why?

Strengthens White to no purpose.

Small.

and the following plays weaken the G-10 stone. Better to sacrifice the C-14 stone, if necessary, strengthen Black's center, and reduce White's huge moyo.

Main focus: Think big. Attack big.
