Hello guys!!! My shadows are smoother from what i want.
Can you help me? My shadows are in the second picture and i want them like the first.
Thank you for your time! 
What are your current light settings? It also looks like your scene has additional meshes and that can also effect your lighting since the objects will interact with the falloff and light bouncing off of them will have an effect.
Try adjusting your Light Falloff Exponent and Indirect Lighting Intensity.
