A high-end corporate winter greeting card, horizontal 16:9 widescreen format. The background is a solid deep blue color, like a dark winter night sky.
In the center of the composition, on a frost-covered window pane, intricate frostwork and snowgraphy form a detailed Christmas tree. The tree is 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, slightly blurred and out of focus, a real green Christmas tree is visible, decorated with warm, glowing bokeh lights.
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 background on the sides must remain the same solid deep blue color as the center.
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.
