I just purchased this very cute book, "I Love You, Daddy," by Jillian Harker.
The story is sweet, but what caught my eye was, of course, the illustrations. Newly added to my favorites list, UK illustrator Jillian Harker has such a nice, loose style. It looks cartoony, but definitely hand drawn with a sketchy feel. She works mostly in pencil, with watercolor washes for color. I looked her up on Amazon and found quite the collection! Apparently she had been doing this for a while. Great Job Kristina, if you're reading this!
