I create cinematic, anime-style action animations that look powerful, emotional, and memorable. If you want dynamic fight scenes, dramatic camera movement, and a 2D-anime feel using 3D, you’re in the right place. What I specialize in: ⚔️ Anime-style cinematic fight scenes (high impact, sakuga-inspired) 🎥 Dynamic camera work (handheld, low-angle, smash zooms, follow cams) 🌀 3D → 2D anime look (stylized lighting, compositing, impact frames) 🧠 Story-driven action (not random punches — every hit has meaning) 🤖 AI-assisted workflows to save time without losing quality Tools I use: 1.Blender (animation, lighting, camera) 2.After Effects (compositing, motion, FX) 3.Mixamo / custom rigs 4.AI tools (for faster iterations, not lazy results)
