Concert artwork depicting a poster for the band "Rabbit", featuring a single girl amidst a theme of broken hearts and skulls. The color palette focuses on vivid shades of purples, pinks, and blacks. The art style showcases black silhouettes set against an Ultra High Definition and High Dynamic Range (UHD, HDR) quality in 8K resolution. The character, inspired by a "Dark Sushi Mix," is creatively illustrated, emphasizing a mystical and edgy aesthetic, maintaining a unique yet striking appearance. The design avoids any undesirable traits such as duplication, disfigurement, or any form of mutation. The poster should be clean and clear, free of low-resolution issues, visual artifacts, and unnecessary text or logos.
