Animate this original artwork as a refined five-second website hero media asset. Low clouds and mist drift around the exact tall tower; sunrise glows gently on the facade and city windows. Preserve buildings and perspective. No camera orbit. 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.
