yomi is too cool to smile B)

Excellent

:) Good job

I thought Chiyo's head came out a bit distorted in regards to shape. This could be partially attributed to the way the inside of her mouth is drawn, which kind of throws her off balance. Another head that I'm a bit displeased with is Sakaki's. Because of the positioning of her features her head seems squashed.
I absolutely love Tomo's expression, you did a great job on her smile. You also did very well on Yomi,
I find Osaka severely indeed of a spacey expression. She looks way too aware here, I recomend you hit her a few times with a bat.
