Eighteen Expressions Worksheet

I started doing these expression exercises using the 25 Essential Expressions worksheet found here: [link] But I found there were expressions I was missing and a few whose differences were subtle enough to be duplicates. So here's my version with eighteen expressions. Please feel free to use this worksheet on your own characters. I hope you find it useful.

EDIT: You can find an incredibly useful tutorial on emotions and facial expressions here: [link]
