Jim dine

 This is my tool, it is based of Jim Dine's abstract art. I tried to do a hammer. but it failed so I did a knife because it was better then the hammer because it has less different shapes. this is how I did it.
Step 1. do a outline with pencil
Step 2. go over it with charcoal.
Step 3. make a shadow around the knife
Step 4. do whatever more designs or things.

Have you done anything like this before?
