I have no idea. Looking at half the time to clarify that you add too much detail on the pages, making it hard to read when working in black and white, you can make it where the character blends in the background easily. My favourite pages are the last pages where I can tell which is the character and the background. and sometimes I can't tell what part of a character is what. On page 5, you introduce a character. I don't know what part of his face was or what that was—a hat or something.
