Scale of things in general looks off - barb wire, rebar in concrete, metal fence poles. Light looks like a completely different style and out of place - a spotlight could look better or something more industrial? Don't understand the brick foundation at the base of the pillar, have any reference for this? Concrete pillar…
The concrete pillar seems very soft, like it was melted away. Check out this reference: http://us.123rf.com/400wm/400/400/opasstudio/opasstudio1208/opasstudio120800054/14947772-broken-concrete-pillars-and-steel-structures-seen.jpg I would also throw more rubble down on the ground around the base, and smaller rocks to break…
Good progression, it's coming along. The barb wire is far too uniform though in the latest update. Also, not sure if this will be something you do entirely in the texture(s), but it seems kind of strange having a heavily damaged brick/concrete pillar when everything else seems in very good condition.
