Expression Chart - Azuma/Erza

I've been meaning to do this for a while, mostly so I could practice drawing Azuma's face wearing different expressions so that I'm ready for when the story hits dramatic moments. But about half way through this sketch I decided to draw Erza as well just for comparison (or maybe I'm still just shipping and can't keep these two apart ). Anyway, I like how this came out; reminds me of a comedy act with the 'Straight Man' being Azuma and the 'Funny Man' being Erza.
