What is an artwork source, because I don't know what to put in that field.

Is it where I got the my idea from in my drawing, if so would a book where I got my idea be ok? Thank you

An artwork source refers to the origin or inspiration for your artwork. It can be the place, person, object, or concept that influenced your drawing. When indicating the artwork source, it helps provide additional information about your creative process and the context behind your work.

In your case, if you got the idea for your drawing from a book, it would be suitable to mention the book as the artwork source. You can include the title, author, and any specific details that influenced your drawing. For example, if you were inspired by a particular character or scene from the book, you could mention that as well.

Remember, including the artwork source adds depth to your work and acknowledges the sources that have influenced your creativity. It helps viewers or readers to better understand the context and inspiration behind your artwork.
