Prompt: A dramatic digital painting of a cybergoth T-Rex standing amid neon-lit rubble, clad in kevlar armor panels and wielding twin plasma cannons, chrome scales and claws glinting under gritty city lights polluted with digital billboards, post-apocalyptic decals and cybernetic augmentations engraved into its armor, captured via long exposure photography in the gritty style of Dan Mumford, imperfections, grime, textures, 8K resolution.
