For this group, I made a lot of models like this one.
But right now at the moment, I am out of inspiration so it would be really helpful if you guys could suggest something I can improve in my models something I could also make.
By the way, the period I am building for is WW1 so if you guys have got any idea I would be really thankful for you to tell me.
trenches, barbed wire, guns, shotguns, war stuff, bunkers, etc.
Hey, I forgot to mention that I am making smaller assets since I am using blender and I am also not good with making bigger models. About the guns, most are already done. Anyway, thank you for your suggestion I really appreciate it and will take it into consideration. 
Not sure if you want models for WWI (guns and stuff) or for furniture and stuff during WWI (1910 - 1920). If it can be anything I would do some radios or old cars, maybe throw a train or airplane into the mix.
Yeah, that sounds like a good idea I will consider that as well.
