Thankyou all for the supportive comments, esp lightning - I worked hard on getting the lighting right, I was aiming for an early morning sunrise effect ( I miss the old way of doing it so you could see from on high where the sun was in relation to the camera and the terrain)
Also appreciate the tips, and I have printed out more of the very helpful Help Files to master the next steps. This weekend is a 3 day one, and I hope to dedicate some time to TG
