Regular weekly art workshops are held at Willersley Castle Hotel, an historic Castle set in the Derbyshire Peak District set in 60 acres of grounds surrounded by stunning views of the Derwent Valley in the Derwent Valley Mills World Heritage Site. About Denise Cliffen - I have a relaxed and informative approach to working with acrylics and mixed media. I was a professional muralist for 11 years, specialising in trompe l'oeil (trick of the eye) techniques. Although photo realism painting in acrylics was essential in creating a painting illusion, I have also worked more recently with impasto and mixed media using acrylics. (I was a former member of the Association of Professional Muralists and has appeared on television and radio)
