Design modern abstract piece with pastels like lavender.

Design a modern abstract piece with gentle pastels like soft lavender, misty green, and light sand. The composition should feature smooth gradients and blurred edges, with flowing forms that seem to dissolve into each other. Focus on creating a dreamy, ethereal quality by layering translucent shapes and soft textures. The artwork should evoke tranquility, with an emphasis on harmony between the shapes and colors. Keep the overall feel light and airy, with a minimalistic approach. --ar 2:3
