abstract collage vector illustration portrait

Create a vertical 2:3 portrait composition of a [bold abstract collage] that fills the frame with interlocking patterned shapes and layered color fields. Place a large black-and-white vertical striped block in the upper-center, polka-dot halftone patches in the upper-left and lower-left thirds, and two grid-pattern panels in the center-right and lower-left to anchor geometry. Leave a small cream rectangle at the exact center as negative space, with generous margins so the background occupies nearly the whole image plane. Scatter [bright organic blobs] in cyan, pink, yellow and royal blue across the mid and lower thirds and overlap them with the patterned blocks. Add sparse [black ink squiggles] and short curved strokes that cross the center and upper-right to introduce hand-drawn energy. Render as clean vector-style art with flat fills, crisp edges, visible halftone dots and solid black pattern work, keeping contrast high and textures graphic for wallpaper-scale reproduction.
