Bank note

This is my banknote I made for the art lessons.
We had to use East-Indian ink.
We weren't allowed to use colours, only black.
The assignment was to make a new banknote, we could make everything we want, I chose to make some sort of tentacles.
There are some totally black parts in my banknote. On that places I dropped some ink, and I decided to make it all black.
I filled up the background with dots, after my teacher said so.
Personally I think i did pretty well, I'm only not that good with ink.
