coffee foam crescent 3d model

Realistic thin layer of coffee foam bubbles floating on the surface, concentrated mostly along one side in a curved crescent shape. The foam consists of many small and medium round bubbles, semi-transparent and glossy, with warm beige, light caramel, and creamy tan tones. Bubbles are irregular in size and density: smaller dense bubbles near the edge, slightly larger scattered bubbles toward the center. The foam looks delicate, natural, and freshly formed, with soft highlights on the bubble rims, subtle translucency, and uneven organic distribution. No liquid surface, no cup, no background, only the foam bubbles isolated. Photorealistic macro detail, soft lighting, natural coffee foam texture.
