How to reduce shadow?

Hi, guys. How can I reduce the shadow? I want it like on referal. But one problem - no post production, only render! Thanks!

try making the plane a bit reflective as in referal

Here, still not what I need. I got reflection, but the shadow still hard.

either disable shadows, or, use bigger/more lights.

You can also try something like this:

This makes the material transparent for shadow rays.
The color of the Transparent shader controls the intensity of the shadow: White = fully transparent = no shadow, black = fully opaque = full shadow.
