I did a digital drawing of Stonehenge on Salisbury Plane ages ago and I’ve tried to add a misty, foggy, mysterious effect over the top of the original drawing. Because I drew it in layers, the image in the bottom layer shows the stones and this stayed in place so I could distort the upper two layers of black that I had added and then a blueish grey with a smudging tool. The overall effect is slightly spooky, I could imagine shadowy figures or spooky silhouettes detaching themselves from the stones and moving towards anyone visiting the ancient site. What ghosts of druids reside there?
