Create the front of a charming watercolor Halloween greeting card for a child, on pale cream watercolor paper with faint visible grain. Use a soft palette of cream, peach, pale lilac, pumpkin orange, warm black and pink blush. Gentle, even flat light; only small soft highlights and no dramatic shadows. Paint loose transparent watercolor washes with softly rounded ink outlines. Set the headline prominently in the upper-middle, centered and split across two lines exactly as: “Happy Halloween,” and “Mia!” The lettering is friendly rounded handwriting, as if drawn by hand with a medium-thick round-tip marker: consistent stroke weight, softly rounded terminals, natural slight irregularities between matching letters, and casually human spacing. Use rich pumpkin orange for “Happy Halloween,” and warm black for “Mia!”, with subtle pink-blush details. Keep every letter crisp and easy to read. Place a smaller centered line beneath it, exactly: “Wishing you giggles, treats & magic” in the same rounded handwritten style, in muted lilac. Keep generous open cream space around all lettering. Give the lower portion a clear illustrated subject: one small, round, smiling ghost with dot eyes and rosy cheeks, nestled between two friendly jack-o’-lanterns with simple happy faces. Surround the edges loosely with a sleepy black cat, candy corn, wrapped sweets, tiny bats, small stars and a crescent moon. Let these motifs frame the open center without crowding or obscuring any words. Keep everything sweet, hand-painted and child-friendly, with no die-cut sticker borders. No extra text, lettering, border, or watermark.
