Main focus: Getting enclosed, even if you make small life, is usually not good.

Edit: I have been thinking about what lost the game. No one thing, OC. Black came out of the fighting on the bottom side behind. Then

, although joseki, was passive.

gave Black chances, but

should have been the jump attachment, attacking both sides. Then,

, although maybe OK in itself, led to a complicated position where Black had difficulties. Finally, at least as far as I looked, the hane,

, was an overplay, leaving Black with too many weaknesses.
