I sat down with these and finished them up. First thing I did was stir my matte varnish really, really well! I used that to cut the glossy shine down and give a nice matte surface for the pigments to adhere too.
First the dust up. I applied some dusty colored pigments to the top surfaces and the bogies and tracks. I wet that down with white spirits and then wiped off the excess with a makeup sponge. Maybe a little heavy but not bad.
I followed that up with some more pigments. This time I used the Pan Pastels and applied three layers.
