;W[qf]C[I think this game was decided by small increases over the whole game, not necessarily by a huge point swing.
I would like to point out two things throughout the review:
(A) Too loose shape used while fighting
(B) Too tight shape used while trying to surround strong groups
You played very well in the late endgame.]

White has 2 corners (more or less), and black has 2 corners.
Black's corner around r18 has the problem that it is open to the other side. So it will not become so big.]
