Vincent Di Nguyen is an illustrator who's work is often seen in children's books. He grew up in Houston, Texas, and came to New York City to attend the School of Visual Arts. He is a member of the art department at Bluesky Studios, the makers of Ice Age and the film Robots. His work method consists of painting in general.
Some of his clients include Barron's Publishing, Condordia Publishing House, GIA Publications, Harper Collins, McGraw Hill, Marshall Cavendish, Scholastic, Simon & Schuster, Sterling Publishing, Walker & Company, and Weekly Reader.
His style is very interesting to me in that it really portays a child's world well. Nearly every character is small, and there seems to be a sense of exploration in most of his work.
