I created the mud by mixing Joint-Compound with paint. Static grass, Woodland Scenics (light green), was pressed in the wet Joint-Compound. Enviortex Resin was poured down the mill race I am not sure if I should leave it or add artist's gloss medium to create waves. Balsa wood was broken then stained or painted, it depended on the piece. The bridge was built/stained then I pulled of many planks to give it a gutted look. I glued in some pebbles as a stone base, the pebbles were covered in Joint-Compound to give them the appearance they had covered in mud many times.
