Animate this original artwork as a refined five-second website hero media asset. Soft clouds drift behind the exact black-and-white brutalist tower; subtle daylight glides across the concrete texture. Preserve rigid architecture and original framing. Preserve original identities, proportions, palette and materials. Locked camera unless explicitly specified. No zoom, cuts, text, UI, new objects or distorted anatomy. Continuous restrained motion; begin and end near the same composition where physically plausible.
