Create a promotional poster showcasing professional image editing and graphic design services tailored for diverse needs. The design features a sleek, modern aesthetic with a gradient background blending deep navy blue and vibrant colors. At the center, display a collage of visuals representing different services: a vibrant flyer, a polished social media profile, artistic cake decorations, and cheerful children's illustrations. Use lighting and shadow effects to add depth and realism. At the top, include 'SERVIÇOS DE EDIÇÃO E DESIGN GRÁFICO' in bold uppercase sans-serif font, with a bright yellow and white color combination for impact. Below the central collage, add the text 'Criamos para todos os segmentos!' in a friendly cursive font. At the bottom left, display '@designespecialista' with a social media icon, while on the bottom right, include 'Contato: 123-456-789' with a phone icon. Subtle dotted patterns, brushstroke textures, and '+' symbols in light blue and yellow are used throughout for a dynamic and creative feel. The overall design exudes professionalism, creativity, and adaptability."
