Masterpiece, best quality, ultra-detailed 8K image of an absurdly intense battle scene in the afternoon, rendered photorealistically. A close-up shot captures a dynamic angle of a robotic mech, devoid of humans, gripping an assault rifle with both hands. The mech's shoulder weapon features missile pods, with flames and smoke rising from the nozzle as each bullet is fired, causing the weapon to shake from recoil. Practical lighting enhances the realism, focusing on the action with a blurred background. Sci-fi elements include nozzle flash and fire, motion blur, and realistic combat details like dust, sparks, and explosions from the firing.,fantasy robot
