3D Model: Create A Detailed 3D Model Of Echo Sprite, A Mystical Enemy For A Fantasy Metroidvania, Inspired By A Stylized, Hand-painted Ori-like Aesthetic. Design With A Strict Side-profile Silhouette, Featuring A Small, Playful Ghostly Form With A Shimmering, Ethereal Outline, Using Vibrant Purples And Greens. Ensure A Balanced, Smooth Shape With No Distorted Or Humanoid Parts, And A Faintly Glowing Center. The Model Should Have An Optimized Mesh For Animation, With Translucent, Shifting Edges That Suggest Motion. Include Fine Spectral Wisps And Light Gradients, Evoking A Forest Threat In A Non-realistic, Artistic Style. The Design Should Support Versatile Poses, Such As Hovering With A Sudden Charge, Avoiding Detailed Anatomy. Focus On A Mystical, Painted Enemy Look, Ready For Texturing And Rigging, With A Dynamic Yet Lightweight Presence.
