The design features a striking silhouette of two figures in dynamic poses against a black background. One figure appears to be casting a spell, indicated by the upward thrust of their right hand, while the other figure seems to be recoiling from the impact, with their body twisted and arms outstretched. Above these figures, the text "Expecto Patronum" is prominently displayed in a stylized font, suggesting a theme of magic or spellcasting. The use of black as the primary background color creates a dramatic contrast with the pink silhouettes, emphasizing the figures' actions and the overall mystical atmosphere of the design.
