Animate this original artwork as a refined five-second website hero media asset. Water ripples animate the reflections of the exact waterfront towers, a few window lights gently vary and clouds drift slowly. Preserve the skyline, buildings and 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.
