Good concept on this dio. Fire is very difficult to "model" but you have done well here. I like this little scene. The pole/wires are very authentic, as is the wall with the posters. I like your use of various sized rock/gravel to add interest to your ground cover - nice work.
A couple of things for your consideration.
The first thing I looked for was an injured/fallen figure/s. This would add a bit more realism to the scene and would help identify to the viewer what nationality they are looking at in your scene, ie. U.S., German, Soviet etc.
Also, as hot as fires get, some scorch marks on the nearby grass and ground would be appropriate, as are the scorch marks to the wall which you have already mentioned.
This scene is very interesting and well done. Please keep us posted as you move through it. Thanks.
