Random college doodles - Fun

Well.. these are all doodles done during class. On the top left is our Concrete B teacher and the top right is some classmate with a weird sleepy face.

The other ones are pretty random... the face came out of thin air, the bald guys is based on some Assistant Teacher and the girl was a random doodle that started to take manga proportions and was turn into that.

The red stuff was added by my friend while she was bored.

Enjoy.
