(First one is Jorunna parva , last one is Glossodoris misakinosibogae)

1. Rough sketch.
Red line is animated part.
There is small color thumbnail at the top.

2. Paint
Middle one is the focal point. So I paint it's body most brighter and gave it a red point.
3. Animating

4 frame. I thought it's too fast..

So I add 2 more frame (6 frame now).

Here is painted version.
Now I add more animation effect..

I gave a movement to their tentacles (Well, Actually it called rhinophores & branchial plume)

+ Add little bounce.

+ Add background twinkles effect & shadow, eye blinking!
Thank you!
