Rig & Staging
The rig I’m going to use is this free rig. It has a Ninja cloth for the character. So, I think it should be a good expression of soul.

For the scene I use a stadium with tracks for athletic running. I use a HDR as my lighting and background resource.

But the view is quite strange because of the HDR. It feels like the stadium is floating in the air.

So, I build a pipe to surround the stadium. In this way, I will get rid of the grass. Also, it feels like the pipe is an outer wall of the stadium.

First Shot
My first shot is a zooming out camera animation. The purpose is to tell where the story took place.
