This is a 3D printed Resin base from BiteTheBullet Studio. I’m going to show you the steps I used to paint it.
I used a transparent burnt umber acrylic ink from Liquitex to give the entire base an earth tone base, concentrating extra ink on the log and base of the plants (shadowed areas).
I then dry-brushed a grass green over the “turf” and lichen areas, avoiding the log and plants.
Finally I used a black wash on the log to darken it and highlight the cracks and bark texture. (I’m specifically using the black wash from the Vallejo Game Color Washes pack, but any black wash would work.)
