'ello 'ello 'ello !!!
What a beaut, mate 
 
I was not wrong when I said you are the sifu of dioramas, not to mention scratchbuilding!!
But....since you said over the phone yesterday that you wanted some critical comments, well here goes....  
 The dents/holes/roughness of the wall..I dunno...do they look a wee bit oversized in scale? Also, you might want to lighten the stones here and there. The plaster also looks a bit too thick in scale.
Also, the doorway looks kinda narrow, and the interior floor tiles look too pristine, considering the state of the damage to the walls...
Of course, what do I know LOL LOL  :-)  I need to take up lessons from you actually

Adios!
