Following the above advices, you will not be able of landing without consistency.

Then, crossed wind landings will be easier to master.

Use rudder to correct alignment rather than aileron, especially when approaching too slow.

Use rudder side to side also to bleed off excess of approach speed.

A bouncing landing is always a landing at excessive speed (too much energy, able to flex the landing gear enough to make it react like a spring).

A crashing landing due to early stall is always a landing at insufficient speed, mainly forced by up elevator at final.
