Things to consider:
- I measured the proportions but lost track of them and ended up leaving the page.
- The angles of circles is tricky. The top part of the grinder is at the wrong angle.
- Perhaps I should try finishing these drawings off properly with clean lines. I want to keep the sketches brief, though.
An attempt to see where I went wrong. These lines would have been useful throughout the drawing. Even with the guides, the circles are tricky. Need some practice.
