Viola utilizes a selective color technique to pull the eye toward the double-decker buses as they traverse Westminster Bridge. By stripping the surrounding cityscape of its natural hues, the artist emphasizes the structural grandeur of the Houses of Parliament and the clock tower, framing the scene as a dialogue between stone permanence and the fleeting transit of daily life.

The portrait orientation heightens the verticality of the architecture, allowing the expansive sky and the bridge’s masonry to frame the mechanical rhythm below. This perspective explores the constant flow of the capital, turning a familiar travel sight into a grounded exploration of urban character and British heritage.
