RAKIB Social Media Design Poster

Create a vertical social media promotional poster for {argument name="brand name" default="RAKIB"}, advertising {argument name="service line" default="Social Media Designs"}. Use a deep emerald-green studio background with soft smoky abstract waves and a subtle glowing aura behind the headline. Center a smiling young Black male designer/marketer seated in a modern gray armchair, wearing a pale sage-green button-up shirt and beige pants, holding a dark tablet with both hands. Make the portrait realistic, polished, and commercial, with soft front lighting and a confident friendly expression. Canvas and layout: portrait 2:3 ratio, poster-style composition. At the very top, place the huge uppercase word “RAKIB” in bold sans-serif letters, glowing pale mint-white. Directly below it, place “Social Media Designs” in an elegant white serif font. The person occupies the center lower half, overlapping the floating content cards around him. Floating cards: include exactly 4 tilted Instagram-style post mockup cards surrounding the subject, each with a white/cream background, rounded corners, tiny social icons, and the small header name “haris designs” with a green circular logo. Card 1 at upper left: headline “Grow Your Brand With AI,” with plant imagery and a green call-to-action pill. Card 2 at upper right: headline “Creative Content That Converts,” with a circular green interior/product image. Card 3 at lower left: headline “Design Smarter Not Harder,” with a leaf image. Card 4 at lower right: headline “Stand Out Stay Ahead Go Viral,” with a plant image. Keep all card text small but readable enough to imply social media design templates. Bottom feature strip: add a dark translucent green bar across the bottom with exactly 4 feature groups separated by thin vertical divider lines. From left to right: an AI/star icon labeled “AI-Powered Creativity”; a lightbulb icon labeled “Eye-Catching Designs”; a chat bubble icon labeled “Engaging Content”; an upward bar chart icon labeled “Grow Your Brand.” Visual style: premium digital marketing ad, realistic portrait combined with clean UI mockups, mint-green glow accents, high contrast, crisp typography, professional Instagram growth branding. No watermark, no extra logos beyond the mockup headers, no additional people, and no clutter.
