Here are a few quick shots of an apoxy sculpt base. First, the sculpted bits...
And now for the painting. It was fairly basic. I had a grey, a brown, a yellow, and a seafoam green. Using a larger brush and working rapidly, I started out with a yellow/grey mix . The grey/brown mix was used on the rocks themselves...
You can see the seafoam green mixed in with the grey on the upper surfaces of the rocks. Eventually, I mixed in a yellowish white to begin highlighting them.
The highlighting continues. I also mixed this light color in with the yellow/grey mix to highlight the 'ground'.
At this point, it was ready to be shaded and glazed darker. I used a black, a sepia and a bit of green. I focused on the lowest areas making sure to vary how much green or sepia was used.
Here's the finished results!
