The image displays a nighttime scene on the River Thames in London, United Kingdom, viewed from the deck of a vessel. Tower Bridge is prominently featured in the background, illuminated with white and blue lighting across its towers and suspension elements. The London skyline, including several illuminated high-rise buildings, is visible beyond the bridge. The dark river surface reflects ambient light. In the foreground, approximately ten individuals are visible on the boat's deck. Many are dressed in various costumes. On the far left, a person wears a scarecrow costume consisting of a dark green top, a straw-like collar, and a dark pointed hat. Slightly right of center, a person in an orange witch costume with a pointed hat holds a blue denim-like bag. Next to them, a male wears a white sailor's cap with text (partially obscured, possibly "AHHOY") and a striped top. Further right, a male wears a purple baseball cap, a fake black mustache, and a purple garment. Other visible individuals include a female wearing glasses and a black top with a yellow Batman logo, a male in a dark suit and glasses, and a female with green leafy adornments on her head. A tall white mast and associated rigging of the boat are visible on the left side of the frame. People are standing and interacting on the boat's wooden deck, some holding glasses with beverages.
