Nice diorama overall. I really like the B&W pics, as they give a quick impression of an old Hollywood WWII war movie (like To Hell and Back). Positions of the figures is good, accept maybe the tank crew, as they look very exposed to enemy fire.
Vehicles look good too. I like the weathering you did on the M4, and the Willys.
Your ruined house, and the rubble look too neat. Take a look at a real building after a fire or after being demolished. Other then that, your diorama looks fine.
If this is only your 3rd diorama, you have done a great job. Keep up the good work
Cheers !!
