Thanks everyone for looking in.
Chas. I had not come across the artist you mentioned so went and had alook. Not quite my style, and I assume the paintings are traditional methods.
All painters devop differently over the course of their interest and I recall meeting a well know railway painter down here in Devon who was on a professional visit with his camera and I subsequently purchased one of his publications. They were beautifully illustrated paintings which he did disclose to me sometimes took three months to finish. They were 30x24" oils and included every rivet on the bumber bar.
My effort above took around 3 hours on a computer and quite content to evolve these days to that proceedure, not much detail but hopefully pleasant to look at.
