I'm a huge fan of Mark Hearld's work, I have his beautifully printed cards by Art Angels dotted everywhere in my house. The collages are fantastic, I love the colour palette he uses, and the lithographs have that quality of line that is so lovely. Here are some examples from Art Angels website and a gallery that sells his work, Godfrey & Watt.
From Godfrey & Watt Website: 'Mark Hearld was born in 1974. He studied illustration at Glasgow School of Art followed by an MA in Natural History Illustration at the Royal College of Art. His work is based on his observations of the natural world, influenced by mid twentieth century Neo-Romanticism and the gaiety of 1930s Modernism. He is inspired by British artists such as Eric Ravilious, John Piper and Edward Bawden.
