Dragonslair Banner

I sketched out the cat silhouette and then outlined it with masking fluid. I didn't make a particularly thick outline with the masking fluid, just enough to contain the liquid. I also masked out the moon. Then I wet inside the masked outline with water and, using just violet, added in pigment until I had something resembling a cloudy night sky. I carefully added a few stars with a white pen and some acrylic ink. When it was completely dry, I removed the mask.
