Lion - logo Design

This is a simple logo, representing a lion (Of course). This logo was created with pen tool only in Adobe Illustrator!
Please comment, and give me some critique and tips so I can improve!

Note: As you can see have I let the line from the pen tool stay there (when I used o+alt, to duplicate the one side of the head) because it's meant to show that you can just make the first half of the head and after that copy it.
