This design features a black and white illustration of a mermaid with a tail, surrounded by water. The mermaid is depicted with a smiling face, and the water around it appears to be splashing. Below the mermaid, there is a banner with the text "I'M REALLY A MERMAID" written in a playful, cursive font. The overall style of the image is cartoonish and whimsical, with a clear emphasis on the mermaid theme.
