Design a highly detailed 3D miniature diorama of a cozy creative home workspace scene, presented as a collectible scale model. Use an isometric 3/4 top-down perspective with a 35mm equivalent miniature lens look. Keep depth of field shallow but readable, with soft background falloff. Make the entire scene feel handcrafted, like a premium resin architectural model. Set the environment as a warm living room workspace. Place an L-shaped sofa as the central anchor of the composition. Seat a man on the L-shaped sofa with relaxed posture. Place an open MacBook on his lap with a subtle screen glow. Position a Korat cat lying calmly next to him on the sofa cushion. Drape a soft folded blanket beside them. Mount one electric guitar, one classical guitar, and one ukulele on the wall behind the sofa. Place an additional ukulele resting casually on the L-shaped sofa. Hang framed paintings and art prints across the wall in an asymmetrical layout. Include a cat ladder mounted vertically along one wall. Position a medium-sized coffee table in front of the sofa. Place a small stack of books on the coffee table with slightly varied sizes. Use warm ambient indoor lighting with soft overhead illumination. Add subtle practical light sources like a floor lamp glow to enhance coziness. Keep shadows soft and realistic. Render all materials as tactile miniature materials: matte painted walls, wood grain texture on instruments, fabric texture on sofa and blanket. Ensure visible scale cues like tiny base platform edges around the diorama. Maintain high detail, soft cinematic grading, and cohesive handcrafted realism. Ensure visual impact, coherence, and stylistic integrity. No labels. No text.
