A magical tree that grows strong and lush.
I am so happy that this cut was successful.
I was very happy.
As for the technique, my goal was to make a cut that goes around.
but for the artwork, it was about this cut.





All characters and other objects are in only one piece.
They are stacked, shifted in position and placed on a 3D background.


Then, add light and shadow by compositing, etc., and you are done.
