Sounds like a magical moment for you! Very nice drawing!
Yes, there are such moments and for me always women. Eyes, smile, some "not of this world" expression. I had such experience on one day in the train to my workplace. It was the bicycle section where you can sit if you fold some seat down. I left my bicycle on the side. A woman seated on the other side and without thinking and looking around i sat down directly opposite to her. Then i looked at her face and saw that small smile, the clear eyes and she looked back absolutely calm directly into my eyes with a little grin, no laugh down just a confident honest smile and i was not prepared for that piercing glance and got nervous and looked away. I didn't know where to look. I'd never saw such self-confidence and inner calm by a woman and was just speechless and nervous. She noticed that and as she was up she gave me a last sympathetic smile and left the train.
