12-Minute Dark Animated Thriller

I have a complete script for a 12-minute YouTube thriller and I want to bring it to life as a dark, realistic 2D animated film. The tone is tense and cinematic, but I’m choosing animation over live action to control atmosphere, lighting, and pacing without the limits of on-set production. What I need from you is the full package: storyboarding, illustration, animation, voice-over, sound design, and final assembly. Your animation style should feel grounded and gritty—think heavy shadows, nuanced textures, and fluid character movement that pulls viewers into the suspense. Audio is just as important. The narration must be delivered with the right emotional weight, the background score should steadily build tension, and every door creak or heartbeat needs to land in sync with the visuals. On-screen subtitles/captions are required for accessibility as well as engagement. Deliverables (all mandatory): • A fully edited 12-minute 2D animated thriller in dark realistic style, ready for upload (H.264, 1080p). • Professionally recorded and mixed voice-over narration. • Background music and spot sound effects mixed to broadcast-safe levels. • Burned-in English subtitles plus separate SRT/VTT caption file. • All project files and assets so I can make future tweaks if needed. The finished video must be original, license-cleared, and compliant with YouTube’s guidelines. If you excel at moody lighting, cinematic pacing, and polished audio, let’s make this story unforgettable.
