Children's book about a lab and his magical blankie

C'est ce que Catalyst Athletics recherchait dans leur illustration design

Looking for a main character illustration for a children's book about a White English Lab named Blue. When he was a puppy he was scared so he needed his Blankie to make him feel safe. As he got older, him and Blankie went on many adventures to stand up to bullies, save animals, and learn to be strong. So, for this task, I am looking for a fun illustration of what Blue and Blankie will look like as a character. And then from there would like to create full illustration work for the book. After picking the main character illustration, I would like to create a cover and approximately 8-12 illustrations that will include supporting characters.
Attached are some photos of Blue and his Blankie Voir plus
