Another way to align your spine and the four points of shoulders and hips is to stand and walk as you imagine your arm pulling and lifting a heavy load like buckets of water. This will naturally align your spine to carry the load without harming yourself and relax the shoulders and spine accordingally.
If you lack in imagination or want to try this a few times in another way take a chind in each hand or something like 20 kg and walk a few Km. You will learn to walk softly this way as well.
keep breathing and relax the face.
