In general you have a image with potential Yossam but as Kevin said i think your main problem are the texturing and diplacement-bump mapping.
I think you used ray tracing for the objects. The textures do not give real displacement.
There is only bump mapping . Bump mapping is good from a distance but from close range it does not look good (in any program).
A little too much bump map value and it can look bad from a distance too. So you should use it with caution.
Bump mapping does only cheat the displacement. If you look at the close column the edges are straight.
You could get away with the bump on the two far away columns with just a little lower value maybe(but i would change them too) ,
but the close one is problematic. I think the texture you use is not big enough and in this range i would use real displacement anyway.
You can model the displacements as real parts in the object if you can model , or turn off ray trace for objects in TG2 and see how the micro render look would turn out. TG 2 would then render the texture as real displacements.
I think the other objects parts suffer a little from these problems too (strange shadow under the fence on the far side for example).
In short i would turn off ray trace objects and see how it turns out.
You have to make some adjustments for appropriate displacement look probably.
If you can , use better(for displacement made )-bigger textures .
I am curious how it will look if you try it ones more Yossam
