Now for my lighting effects. I am not going to go deep into this as there are numerous articles about this topic. Basically I am going to start painting reds and oranges along the rock where light would hit it. I always make these slightly darker then the original light sorce. If there are deep groves I will often use a watered down black ink to make shadows. Basically I just put a little bit of paint on at a time untill I get the desired effect.

You can see that i need it a little bit lighter twoards the centers of the light reflections. I'll add some orange.

Now I re-check my paint job and fix or smooth anything out. Paint the outside of the base black and glue the mini ontop of the rock.

Have fun!
