“My Invisible Friend, Kevin”...

Professional illustrated front book cover, vertical composition, titled “My Invisible Friend, Kevin” in large playful typography at the top. A charmingly disheveled person stands in the lower center, enthusiastically talking and gesturing toward an obviously empty space beside them. A speech bubble pointing toward the empty space contains only “???”. Kevin is nearly invisible: only a faint translucent, softly glowing creature-shaped outline and subtle distortion of light reveal his presence. Clever visual comedy, whimsical magical realism, quirky storybook illustration, soft pastel colors, warm lighting, charming hand-painted texture. Clear title hierarchy, intentional negative space, balanced cover layout, polished publishing design, intriguing and funny, with room at the bottom for an author name.
