樱花水彩与肌理素材七宫格

High-resolution digital watercolor and texture art: one pure-white-background asset sheet laid out as seven numbered panels, each with a faint gray header. 01, top left: 'branch_01.png' through 'branch_04.png', four sprigs of pink cherry blossom. Painterly and delicate, with dark brown stems and soft pink petals. 02, top right: 'petals_transparent PNG', around 30 loose petals strewn at random; add a few complete blossoms at the cluster's lower right. 03, middle left: 'sky_01.png' to 'sky_05.png', five square tiles of blue sky. White clouds on blue, each tile carrying its own level of halftone dots or pixel noise. 04, middle right: twelve small square swatches in 2 rows x 6 columns, named 'dither_01-03', 'ink_red_01-02', 'ink_black_01-02', 'grunge_01-02', 'grain_01-03'. The set moves from black-and-white dither patterns to red ink spatter and beige paper grain. 05, bottom left: 'paper_01.png' to 'paper_04.png', four tall rectangular strips of fibrous paper in cream, light gray, dark charcoal and off-white. 06, bottom center: three cast shadows. One big square of leafy branch shadow ('shadow_branch.png'), one smaller square of thick foliage shadow ('shadow_leaf_01.png'), and one slim vertical strip of line shadow ('line_01.png'). 07, bottom right: 'mask_diagonal.png', 'mask_soft_01.png', 'mask_soft_02.png' and 'gradient_fade.png', six grayscale gradient masks with smooth black-to-white falloff in assorted shapes: diagonal cuts, soft blobs and linear fades.
