Abstract Ethereal Swirling Wisps Soft Gray

Create an abstract design featuring ethereal, swirling wisps of soft gray smoke gracefully moving across a stark, dark background. Alter the smoke's dynamics to include gentle, flowing curves, and introduce varying opacity levels for a more layered appearance. Replace the uniformity of the smoke with more textured patterns, resembling delicate fabric. Ensure there are no brand references or logos in the composition.
