ideas for a diorama

after finishing my seccond diorama i had some ideas for my next project.
i havent decided wich one to make so i hope the good people of this site can help me.

im curretnly thinking of making an anti aircraft emplacement or 2 or 3 artillery guns in a field and also a diorama of a street with rubble and makesift blockades.

i also had an idea of some french resistance fighters getting ready to ambush or destroy german infrastucture.

bc this would be my third ever diorama i would like to keep it small and maybe use 1:72 scale.

feel free to give any kind of tip or kits that could be used.

Update: after a visit to a hobby shop I have set my mind on my next diorama. It will be a late production tiger 1 undergoing engine maintaince.
