How to paint a backdrop for a model train layout

Here is another backdrop for a model train layout that I painted recently in acrylic, with some notes about tools and techniques. I hope you will find my notes and photographs useful. I am finding the challenge of painting such a wide landscape very good for developing my painting skills. acrylic paints, a palette, brushes, lichen , water and mixing tray

Tools - acrylic paints, a palette, brushes, lichen , water and mixing tray

I use cheap brushes and acrylic craft paint. Some brands are easier to mix, and they go on the board smoothly. Try a few to find a brand that you like.

The scene for this backdrop is a limestone quarry in South Australia, with distant mountains and scattered bushes and trees on low hills. The two large panels of MDF were painted with undercoat and a layer of sky blue interior house paint.

The colours for the background scenery are quite grey. The mountains and the middle area are both mixed from cobalt, cerulean and orange with white. The orange and grey are complementary colours so when they are mixed they become more grey.

I use lichen (which is used for the model scenery) to dip in paint and dab on for leaves and bushes. I find the results more convincing than sea sponges and cork which I've used previously. The small bushes and trees follow the contours of the slopes.

The large trees and trunks for the small trees are painted in a mix of cobalt, burnt sienna and white, using a fine brush.

A small brush is used for some leaves and a larger round brush for clumps of leaves, so the trees don't look too fussy. The round brush was quite dry and the hairs divided to make a useful tool for droopy leaves.

I began the second panel a couple of weeks after finishing the first, and realised it would have been a good idea to write down the combination of colours I'd used as I had some trouble re-creating them. However, I had made a start on the second panel at the end that will join the first panel, anticipating that it could be difficult to match the colours. I also painted a little way back onto the end of the first panel when I moved on to the second one. Anyway once there are some model trees and bushes in front of the join any small differences in colour should not be too noticeable.
