The way the opacity was used to signify the title, "talk" was a really cool visual trick. I like the colors that surround the guys head. The focus on the face makes it clear what the focus of this poster is.
I like this typography design because I find it clever that the text is in the shape of a trumpet but tangled up so it spells the word Jazz. I also love the sort of neon noodle sign look to it as well as that fits the jazz era.
