Alan Langford is a British comics artist who has worked on titles including Super Naturals, Eagle (on Doomlord) and 2000 AD (on strips including Tharg's Future Shocks, Agent Rat and Tharg's Time Twisters).
According to his website, Langford now "works mainly as an equestrian artist, painting horses and ponies in the open tract of the New Forest or Dartmoor in Devon. His love of riding and horses has aided him in depicting these remarkable animals with empathy, vigour and movement. A fascination for Romanies and their horse fairs has exerted a powerful influence on his paintings."
You don't get many equestrian artists, because it's so hard to keep hold of the canvas and paint brushes when on horseback.
