;B[ld]C[Building a wall toward center with m16 isn't very useful here since the center is still completely open.

I'm not sure if you know that white can't be killed there, but try to remember the main purpose of attacking should be to make territory and THEN (and only then) to try and kill.

Since this wall just makes white more solid on top and doesn't make much if any territory it wastes moves.

A big move like F5 or C8 would be better.]
