Most swimmers aren't aware of chin tuck when breathing until they see it on video. Have someone video you from deck as they walk along side, breathe toward the camera. Look for chin tuck, lifting head (2 goggles above surf), entering recovery arm flat and/or in front of head on your breathing stroke.
Another thing you can do to create symmetry in breathing is breathe on one's, i.e breath left then breathe to your right on very next stroke. Do it for two strokes, then go back to breathing on two's. Mix in the breathing on one's frequently and allows you to get more air too. :-)
