Latter two photos. Two art pieces very different textually and visually. I wouldn't tend to think of the headshot in picture one as street art but of course it is. It's a portrait but I'm sure I'm not alone in often not paying those pictures much attention.
I must admit your not alone some of the art pieces I share I get comments from people who walk by them regularly and have never noticed them and I to probably didn't till I got back into photography
