Harriet the Spy sketches

So I'm reading "Harriet the Spy" and aim to illustrate some of the scenes from the book. Here are a few character sketches of Ol' Golly's mom, Harriet and Sport. I'm not sure if these will carry through until the final illustrations but these were the first concepts that dropped out of my pencil. Although, Ol' Golly's mom is pretty close as to how I see her in the book.
