I bet so many people who have only seen the show are questioning why he’s drawn him so different, well, he’s the illustrator of the books which came about 10 years before the show existed and a lot of Horrid Henry drawings are done vastly different than the show especially with the colours, designs, skin tones, clothes etc, so don’t expect consistency in similarity or quality (especially in the most recent books which alot of the drawings are very poor)
