Design a futuristic YouTube channel logo and banner for “MythicMesh Studios,” specializing in innovative 3D animated storytelling. Use a modern palette of deep space purple, neon violet, blue-purple gradients, and chrome silver. Create a sleek glowing 3D logo with advanced sci-fi typography and a floating holographic mesh sphere icon symbolizing imagination and animation. The banner should feature futuristic digital landscapes, holographic mesh patterns, cinematic lighting, soft glowing particles, and immersive sci-fi depth. The style should feel innovative, premium, highly polished, visually advanced, and perfect for a next-generation 3D animation studio brand.
