I'm almost done making a new Game Board for myself.
Here's 2 pics taken from my Iphone over the weekend.
Basic acrylic gray house paint laid down with grit in it.
Then assorted gray, green, yellow and rust colored paints sprayed to break up the gray base color.
The entire board was drybrushed with the base color to break up the spray paint.
Several coats of green weathering pigment mixed with water were laid down to get a base mossy look.
Assorted browns were airbrushed along the rock face to achieve a striation look in the bedrock. The craters were shadowed and the dried river bed was accentuated with greens and browns.
The next step is to continue detailing the craters, fix a few of the striations I'm not happy with, clear coat it and add some grass. Hopefully it'll be done by the end of next week.
