My project in Surrealistic Fineliner Illustration course

What a playful and interesting course!
The courier brought my new liners yesterday. I ordered them through the e-shop. The liners aren't worn out yet, so I couldn't create a gray scale. How did I invent?
- thimble as a safety helmet,
- a needle as a weapon,
- mouse = guardian of the mouse kingdom.
I was inspired by the guard of Buckingham Palace.
This is my first picture. Others will be better :-)

Thank you Redmer for all the great advice and information! I send my heartfelt greetings from Slovakia :-)
