Okay, you asked for more input so here goes:
* Overall nice idea and layout, although overmodeled IMO: flak emplacement during "down time"
* Nice attention to detail...I especially like the camo net and stowed ammo...
* bunker, flak and base are generally well-done...
* The area that I feel needs the most improvment are the figs...the man with his arms crossed is wearing a uniform that I cannot identify----he looks British...the other figs appear to be a Dragon set and are totally wrong for this dio, IMO---I believe they are German soldiers from 1940...And the scene is a bit busy; too many side-bars going on...you probably have too many figures on the base...
Overall, a B-...Please don't take my feedback the wrong way; you have a lot of good things going on...dios are very difficult to make and almost impossible to master...there is so much to a dio, and every element is a chance to screw up...
Looking forward to seeing more work from you.
