Video game spacecraft design turnaround plate, photorealistic CG concept art, on a plain light grey background. A crystalline alien vessel: a cluster of long faceted crystal shards around a glowing core, held in a dark metallic cradle of thin arcs, energy veins running along the crystals, no windows, no visible guns, a ring of light at the rear as its engine. Original design, not from any film, series, anime or game. No logos, no insignia, no flags, no text markings, no numbers on the craft. Real size 60 m long, 30 m wide, 26 m high. Layout: big orthographic side view across the top, front view, rear view and top view below, and a 3/4 front hero view; callouts naming the main parts and dimensions in metres; material swatches (hull paint, bare metal, heat-scorched metal, glass, engine glow). Rich believable construction detail: panel lines, hatches, thrusters, vents, light wear. No other text.
