So I've sanded back the road to represent a metalled surface. I do have a bag of mendip roadstone which should be suitable! The retaining wall's been painted in a selection of acrylics and pounced with talc and quarry scenic dust. A bit more weathering and dry brushing is required yet.
More hedging has been laid and I've been adding a selection of ground cover, mainly using postiche covered with foam. The second board has had its initial covering of static grass and I'll be working my way down through the boards. Takes a long time to do anything, though I'm quite liking the view down the line towards the bridge.
I'd left a strip of masking tape under the static grass which I can remove so as to add the line side fence later (i.e. when I can't put it off any longer). Next step is an orchard, maybe the up advance starter signal by the bridge and then the Callow Rock stone loading point shelter. A load of brass angle has duly arrived.
