Well, it turns out it wasn't the second batch of Orc or Wolf I ended up painting....
Light was problematic again, so two pics, one under natural light (in the shade, it was suddenly sunny) and one with flash:
I tried to give the spiders a natural seeming patterning on their abdomen, but sadly it just turns out as mottling to the eye. Still looks rather nice though...
As a nod to the old WHQ art, I did two spiders with a skull patterning on their abdomen, did you spot them?
