Banknote

Hello,
We had to make a banknote for Art. You had to put as much patterns in it as possible.
I made a dollar banknote with my own head on it. Here you can see my banknote:

this is the front of my banknote                                         this is the back of my banknote

My mark was a 7.0 and I can understand why it is not that high because I didn't had much patterns
