Mark created this image with a photograph of his Kronosaurus sculpture that he retouched into the background. The background was created with photos plus some rendering in Photoshop. He does illustrations for museums on a commission basis; looking for good clients, not just a windfall on one job. Pictured above is one of the images presented in Pliosaur ART by Mark Musy for sale on the Amazon Kindle e-book website under Mark Musy e-books.
