A refined product mockup showing the Logo Concept deeply embossed into the front cover of a closed leather journal in the Leather Color. Place the journal at a slight three-quarter angle on the Surface Setting, with the Pen Style resting diagonally beside it. Make the embossing crisp, recessed, and naturally pressed into the grain, with realistic edge shadows and subtle variations in the leather texture. Use soft directional window light from the upper left, gentle falloff, and controlled highlights along the cover and pen. Keep the composition spacious and understated, with the logo as the clear focal point. Photograph it like a premium stationery campaign using an 85mm lens and shallow depth of field. Render all lettering in the Logo Concept accurately and legibly. Use the Format.
