Build out your storyboard by adding details, frames, or camera direction, as per instructor's direction. Clean up storyboard in Photoshop and import into an After Effects scene. Create an animatic of the select scene.

Remember that pacing is essential to turn your image sequence into a coherent and watchable animatic. As always, consider camera framing (Close-up, wide, etc) and movement (dolly, push in, etc) for each scene and note what kind of transition (cut, crossfade, etc) happens between scenes. Indicate these technical details in notes or by using After Effects animation tool set. Use of audio elements is optional but encouraged.
