Yes you are right. I noticed that corner is very huge after i already played a.

[Falcord]

Just a small tactical thing, but I think 140 should've clearly been at N11. Reading mistake maybe?

[marvin]

Thanks, i missed this obvious move.

After W plays moves 30-32-34 and B answers defensively, the B side territory is too solid to invade. However there is still a very large reducing move at S8. Note that B probably cannot block at S9, as the cross-cut R9 gets him into trouble (try playing out some variations). So the territory reduction is very large and probably sente.
