Built a small diorama to test out techniques before I hit the main layout

I guess this is technically a layout for tagging purposes?

I’m working on my first layout so wanted to try out my first go at ballasting and static grass on an offcut, thought I might as well complete it into a diorama for displaying models if I want to. Any tips for improvement always welcome, it’s all based from watching YouTube videos so far!

Materials used; Hill is Polystyrene offcuts and plaster bandage Grass verge is Sculptamold Rocks are woodland scenics plaster molded (plus a pebble from my garden) Soil is specialist aggregates universal ground cover Ballast is woodland scenics fine gray Track is an old bit of peco Grass is woodland scenics 2mm light and medium blended roughly for variation, with 4mm light in patches Tufts are WWSCENICS 6mm wild meadow Trees I found in the loft from when I was a kid so no idea I’m afraid.
