I was out and about a few months ago. Finally got around to working on the following materials. 
Here we have a variety of surfaces I manage to mash up together whilst scouting on my adventure to Wilson's Promontory, although most of the hike was grassland and mountains, I managed to spot some interesting shapes that I wanted to capture that were in the area. Hard Mixed Rock, Orange Lichen, Sand Dunes, and the Asphalt in the Parking Lot. 
Enjoy.
