realism cockroach grimy alleyway urban decay

Realism of a cockroach scurrying across a grimy, litter-strewn alleyway, dimly lit by a single flickering streetlamp, surrounded by towering, decaying buildings, with shadows cast by the harsh moonlight, intricate textures of decaying walls and discarded trash, a sense of stillness and isolation, a single cockroach in sharp focus, a stark contrast between the urban decay and the natural resilience of the cockroach, a sense of the cockroach's relentless survival instinct.
