Separadores de libro estilo gongbi

Create an elegant presentation sheet showing a matching set of four to six elongated bookmark design drafts in traditional Chinese gongbi fine-brush painting style, themed on the subject described in the user request. Arrange the tall, narrow bookmarks side by side on a refined rice-paper or soft neutral background with even spacing, each finished with a silk tassel hanging from a small hole at the top. Paint every bookmark with meticulous gongbi technique: fine, even ink outlines, layered mineral-pigment washes in tones such as azurite blue, malachite green, vermilion, ochre, and shell white, delicate gradations, and generous negative space. Give each bookmark a short vertical calligraphy title in accurate, non-garbled Simplified Chinese characters, and add an occasional small red seal stamp for authenticity. Vary the motif from bookmark to bookmark while keeping the palette, linework, and mood unified so the set reads as one collection. The whole sheet should feel like a designer's product presentation board — clean, printable, and gift-worthy. Avoid cartoon styling, thick western outlines, garbled or mirrored characters, watermarks, and cluttered backgrounds.
