Thanks for the nice comments. Really help a lot 😃
Here is some progress. I add a sky light here to make some nice shadow there............ though the tree and lamp have no shadow there as I apply a material with illumination on the floor.
One thing not sure about is the displacement map(tiles) for the icecream cone.
look strange when i apply.
When I auto key a scale value, I found it work in attribute, but not workable in viewport by scale tool. Just wondering why? I have already turn auto key on...
