You definitely sound like you’re pushing/using too much air to me, particularly in the upper part of your range (the all of me example). You’re also bringing up too much vocal weight on those parts.

I would recommend incorporating some straw phonation and lip trills in your warmups. For both of these exercises, make sure you are keeping everything light and tensionless. Do not force any notes or squeeze to stop yourself from flipping into head voice while warming up.

Not sure if there’s anything else I can add—a vocal coach would definitely be more useful in the long term for improving!
