I didn't realize that it needed to be a headshot either. I'll have to change it back
From what you're seeing, it sounds as if Google isn't enforcing the rule requiring a headshot. Until/Unless they do start enforcing it, why change it back? The higher CTR you're getting in the meantime might even boost your rankings and bring even more traffic.
