On a different note, let's discuss
, R3.With the continuation as it happened in the game (R2, S3, S2, R5), you ended up having to protect the cutting point with R5, giving up sente. Then W uses the initiative to ensure his group is fully alive, though from a glance I think W can at least escape to the center even after a tenuki. Doesn't seem like a great result considering you started the corner with a 4-4 stone and a 4-10 extension on one side.
Given that, perhaps you should consider something like R4, to which W probably will respond R3. At that point you have successfully cut off S6 in sente. You can use the initiative to fix with M5, contain the Q6 stone, or there are still lots of big points to play.
Or, if you want to play R3, follow up W's R2 with R4. This fixes your cut point, but leaves the threat at S2 next to take away the W group's eyespace in the corner. If W plays S2, great--once again you have cut off the stone in sente.
Lastly, you could concede W will probably live in the corner and decide that the N4 is the more important cut point. Some moves around there look good to my naive eye: N3 looks sente against the corner group (it enables the double hane), or M5 looks to be both extending from D4 and has a constraining effect on Q6.
