From Jennell Jacquays:
So here it is, the painting that a number of my fans have been asking for … Thornworld, a Spelljammer themed scene for the cover of a Dragon magazine back in the 90s. My original intent for the painting was more complex, but deadlines pushed me toward a simpler rendering. If I can find the original sketch, I’ll attach it in the comments.
The painting is rendered in acrylics.
