My thoughts.

It keeps adding deleted comments when I try to link it as sgf.

:b5:

makes sense
:w10:

Idk if I agree.
:b15:

Might be some shape issues. The bamboo joint threatens to surround the corner or take the base of the two white stones.
:b21:

Agree this looks great for black.
:b23:

forces white to strengthen himself without really strengthening black. Jumping out threatens surrounding either the corner or capping the white group.
:b32:

You can see the 3-3 invasion really hurt the black group at G3
:b41:

I think this move is small. All the white groups here are alive. There are a lot of big points left to take. Enclosure. Or star point on the top.
:b45:

Maybe hane on top first. The two stones aren't very important because the white groups are alive and connected.
:b69:

Compare in game :b73:

with R15 at :b69:

It looks like black is searching for forcing moves which is good because sente is nice. But not all forcing moves are good. For example your variation at :b17:

is a forcing move (atari) but it gains nothing for black. All it does is lose a liberty. So it's not very good.

Instead of directly forcing white with moves like :b23:

I think black can start looking for moves like jumping out at :b23:

It indirectly forces white because it threatens two sides.

Is black in the down-left conner can be killed?

Hi sliderser, see Bill's notes and variations at :b39:

, and

194.

I added a variation on move :w22:

for discussion. What do you think about that variation?

Doesn't quite work, I think. Black connect at O4 and then if white cuts at O6 black can atari at N6 and then capture the Q7 stone.

I edited your suggestion together with some followups in my above posting, but I'm not yet fully convinced. After white blocks at N5 I cannot see a clear way for black how to capture O6,O7.
