I'll give you my first impressions from a quick run-around and some techincal and other suggestions, take it as you will.
1. Overall, I like it. Not huge, not too small... Should be interesting. Personally, I like maps that aren't evenly balanced. I think one side should almost always be fighting up hill on at least one end. I LIKE the fact that your doors don't 'auto-close'.
2. Suggestions:
a. take out the headlights on the trucks in the garage. In their place I would suggest adding a 'short-hanging light' on each corner of the garage, and maybe on in the middle of the front beam. MUCH more realistic.
b. add a 'sound speaker' near the trucks on the road, which I assume are the Allied spawn area. Realism tweak.
c. First building on the left, with the nice stairs... give it a hand-rail...unless a circus family lives in this village

More realism. Same for the other areas of the map with exposed stairs....no one would build that way.
d. last building on the right, with the bay windows. Each bay has cracks. Try to realign the brushes to eliminate the cracks.
- second floor windows are too tall...maybe lower them 16-20 units. IF you want to limit view/sniping you can put partially open/closed shutters on them.
e. forgot this before... the first building on the right, add a railing around the 2nd floor balcony. Realism, and keep your players from suiciding off so easily.
f. add coronas to your red lights.
g. on your metal sliding doors near the 88s, I'd add little handles on top of the doors or something to break up the flattness...make it appear that you 'can' open them from outside. IF you do this, just add brushes and highlight them with the door and right-click/add-to-entity. More realism trim.
h. be careful with the sharp angles in the terrain surrounding the bunkers, could, in some cases trap players. Didn't happen to me, but you never know.
g. maybe some more crates, barrels, miscellaneous stuff stacked/laying about, a little more cover along the road and into the bunkers.
i. one of the houses with the cement basement; I'd give it a dirt floor and where you have the two lights, plop in a couple german/lanters there hanging from the ceiling. It'll look more naturally lit.
j. i'd expect to find a couple MG-42 nests along the way, just for 'looks' if nothing else. Also, maybe some telephone poles/wires leading from the bunker either into the house area or off the map.
k. maybe a background sound effect? filler noise from one of the games outdoor farm type settings.
SO, that's what I caught in about 8 minutes. Overall, I like it. The linear-forced fight is good, in my opinion, helps to stress team play and mutual support for the Allies to penetrate the Axis bunkers.
