HI;
Altough i'm not an expert in diorama building i'd say your dioramas could use some more weathering.
For example the "desert" diorama: I'd "dust" the whole thing,the contrast between figures,vehicle and landscape are to big i think. In the heat of a desert sand poses a real problem,it covers all,gets in the engines,...what i miss in this dio is the heat,the sand,the dirty look.(It could be the pics too). A trick too achieve this efect is the airbrush.Use a lcht yellow colour or tamiya buff and spray it on top op your dio ( no coat,not even a hint of it),it will simulate dust. Another way is to use weathering powders ( Mig Pigments,..).
As is said before i'm not an expert!
