Hi All,
Ok nearly there, I only need to do the sand and then get outdoor pics.
The cliff was given washes of light sand, medium sands and brown sands and then two washes of desert sand. Once the last wash was done I used red brown pastel chalk and brushed it on in random areas.
Once the pastel chalk was added I then used a medium brush and gave the pastel chalk a going over of just plain water to spread it out and also to tone down the red brown.
The troopers were given weathering using light sand paint and pastel chalks so was the dewback, I gave the dewback the same water wash to tone the pastels down as well.
