Create a bold, clean livestream-style emote featuring an acoustic guitar in red and gold colors. Include the word “WELCOME” in large, energetic lettering. Add subtle glowing spark effects and a warm spotlight vibe around the guitar to create an inviting, exciting feel. Style should be vibrant, eye-catching, slightly glossy/cartoonish, with high contrast and a transparent background. Keep it simple enough to be readable at small emote size, with sharp outlines and an energetic celebratory feel.
