Yawning

I've made it during chemistry class. Yeah I was bored and sleepy yet still excited to draw. It was so much based on my situation. I was in chemistry class, it was boring and I was going to fall asleep. And kept yawning just like on the sketch but it wasn't me on the sketch, Because my hair is obviously long and I wear hijab in the school everyday. But, it's clearly a girl with pixie hair cut, yeah I'm kinda obsessed with androgyny girl. Then I had nothing to do besides drawing during lesson.
