Yes, Avebury is a wonderful subject, but it doesn't prevent my pictures from going wrong. Your style is so fresh and clear - deceptively simple, but very effective. I have sometimes acheived a reasonable watercolour, but all the muddy wrong 'uns have made me despair of watercolour. Now I do quick sketches with pastel pencils and work something up with soft pastels when I get home. Tend to invent weather and light as I go for moody stuff like my recent "Seahenge".
