Thanks for taking the time to comment chaps.
The groundwork is a rough coat of Milliput, then coated with white glue(PVA) with a scattering of sand over that. I painted it brown then applied raw sienna, burnt umber and a touch of black in oil washes, allowing them to bleed into each other. It needs, dry brushing, some grass and the pitch marking out.
Cheers,
Carl.
