Ayla facial expressions

I wanted to draw a bunch of anime facial expressions so I drew a blank face and copied it a bunch of times. Then I drew every classic anime expression I could think of and I went through all of my manga books to come up with some ideas.......I like 4 and 6 and 21....ok I like some others ....which one is your favorite?
