Shadows wrong of light look bad

I just can’t get my shadows to look good in one scene.

In scene 1 its looks good and just like I want:

In scene 2 its looks not the same even tho I use the same settings:

In both scenes I use two sided shadows for the mesh and hard shadows for the light.

Any idea why this is the case?

Thanks in advance Max.
