A high-end corporate winter greeting card, horizontal 16:9 widescreen format. The scene is a frost-covered window pane with intricate frostwork and snowgraphy covering the glass. In the center, the frost forms a detailed Christmas tree, decorated with miniature ice sculptures of mining equipment: a BELAZ dump truck, a quarry excavator, a roadheader, a miner's helmet, and a jackhammer. Through the window behind the frost, slightly blurred and out of focus, a real green Christmas tree is visible, decorated with warm, glowing bokeh lights and colorful ornaments.
Extend the composition to the left and right, maintaining the same frostwork style. Add additional frost patterns, snowflakes, and ice crystal swirls on the sides to fill the horizontal frame naturally. The central elements (the frost Christmas tree, the miniature mining equipment ornaments, and the blurred Christmas tree lights in the background) must remain unchanged and in focus.
The overall mood is magical, cozy, and professional. Elegant, ultra-detailed, 8K resolution, glossy crystalline texture, shallow depth of field, horizontal 16:9 format.
