Calm Down

This is a scetch for my next work at school. It's my first still life picture and I drew it just in about an hour.
I hope I can do a good the final version 'cause I don't like to draw big pictures. That's why I draw always on a small area of a sheet (see other drawings).
It's sheldon that I draw bigger ones. But unfortunatley I have to draw it at least two times bigger...
