If I’m honest with myself, I might be procrastinating. I do this whenever there’s a new skill to develop and apply and I’m nervous about getting started. However, I convinced myself that the background should be blended with the landscape before starting on static grass.
The blending started with a small piece of blank backdrop, which was probably going to be obscured by the copse, but why take the chance? So, I squeezed out a small puddle of Yellow Ochre, Hooker’s Green and Raw Sienna and filled in the missing area. Then I had left-over paint, which is a bit like having run out of cookies and still having half a glass of milk left: you need to get more cookies, but not so many that you run out of milk. In this case, the extra milk started spilling onto the ground in front of the background, and I decided I liked the way it helps to marry the foreground with the background. So I carried on.
After living with the fence for a couple of weeks, I’ve realized there is a leading line straight into the background, when viewed from behind the roundhouse. I may yet hide this view with trees in the foreground, but if it remains, I want to both reward the viewer and disguise the background. So, I continued the road and fence line that descends the background with another split rail fence in front of the background. I left an opening slightly past the corner, and I’ve been considering what cameo might complete this scene.

That’s really effective, René.
Suggest you avoid having a cameo here, as it will draw attention to the background rather than allowing it to fade into the distance.
Good point, Simon. Maybe a mid-distance cameo, rather than distant…
