Create a finished, simple portrait birthday poster on luminous white cold-press watercolor paper, 3:4 aspect ratio. Render the exact text, spelled and cased as follows: headline “Happy Birthday Otto”; supporting line “Make a wish!”; small footer “CAKE · CANDLES · CHEERS”. Make the headline the clear focal point, centered and large, written in flowing joined brush-script with thick-thin hand-painted pressure and no serifs. Paint its strokes in transparent aquarelle washes: pale centers with white paper glowing through, darker pigment pooling along stroke edges, fine pigment granulation in the paper tooth, small soft wet-on-wet blooms at joins, and a mix of diffuse and crisp dried edges. Use layered cobalt blue, rose madder, and sap green in the lettering, keeping the forms highly legible. Set the supporting line and footer in small, neat hand-lettered ink lettering in deep indigo, with generous spacing and clear contrast. Arrange the headline in the central area with generous white space around it. Place “Make a wish!” beneath the headline, then the smaller footer near the bottom. Add a few simple hand-painted watercolor doodles around the text: one small outlined star, two tiny stars, and two simple fireworks bursts made from short radiating brush lines and dots. Keep doodles secondary, balanced around the lettering, and clear of the words. Use transparent cobalt, rose, and sap-green washes with varied soft and crisp edges. Let unpainted paper provide every bright highlight; show visible cold-press tooth and tiny white gaps in pigment. Soft, even north-window light, subtle natural paper shadow, clean white paper ground. No extra words, no border, no clutter, no opaque paint, no digital gradients.
