Party Time
You found a good use for those Tamiya brick sets. Those and the sandbags are two sets that EVERYONE has and is hard pressed to find a good use for -
My view of the stone wall is a bit different, the size of the rocks is nice, very authentic, very well executed.
What I see as a challenge (maybe) is the thickness of the wall. The part that is catching my eye is the area around the door. This may be a moot point depending on how much a viewer will get to see a cross section of the rock wall. As with the size, it could just be the photos. Pretty small nit pick.
As with the others - great doors.
