These were animated within two weeks.
Week One: Layout (camera angles)
Week Two: Animation.
Note that the characters already existed and had been set up for animation beforehand.
Also note, the software and animation capabilities (due to the style) were a bit more limited with this.

Timeframe: 2 weeks (after finished storyboard)

Timeframe: 2 weeks (after finished storyboard and opening titles were completed)

These were animated with my current animation software (Moho), which allows for more advanced animation and is a bit faster.

3 days. Two days for dragon creation, set up, and one day for animation and background.

3.5 days.
2 days for wolf creation, 1.5 days for animation, 1 day for background and monster at the end.

1 day for everything.
