Set in a shadowy room, the scene is steeped in sci-fi aesthetics, with precise ray tracing creating a dramatic rim light. Ultra-detailed and embodying cinematic flair, the composition is centered, exuding a stoic, moody atmosphere. The high contrast of Rembrandt lighting highlights her features, enhanced by ambient and lumen reflections. The shallow focus and rtx ray tracing lighting lend an ultra-realistic quality, akin to an octane render, presented in stunning 8K resolution.
