I liked the shot... the only thing I would have changed was to maybe have focused on the sign and had all the crosses showing in the background or beneath. But then, maybe you're right and this is best.
Rather than explaining what this is in your title, I think it'd be more effective if you'd simply titled it "Don't Drink and Drive" or something to that sort. The message.
If you wait until dusk, and get your camera angle lower, you could have really made a WOW shot. This image, is a snap shot of you standing in front of the school. Don't be afraid to try new things. 5 -danny
