Diane Ewen is British illustrator, born in Walsall, in the West Midlands. She has always been in love with art and graduated from the University of Wolverhampton with a B.A. Honours Degree in illustration. Diane likes to create illustrations that are hand-drawn in pencil before painting in watercolour and acrylics prior to embellishing them using Photoshop, but she also enjoys working directly on the computer screen creating her designs. She likes the fact that illustrations are the first things that entice the reader to engage with a book and is inspired by the use of vibrant colour.
