Thanks. Yes, the fog is definitely a problem, but reducing the thickness doesn't really work, and I think a volumetric sphere with cloud texture would add much to rendering time. It's already too big because of the wings. (I put a higher reflectivity, so they stand out more.) I'll try with plop render, though. The texture is intentional. It's a mixture of something with leopard procedural. Mimicry. :-)
