Colors of belgian flag are wrong (if you intended to do that) - its black yellow and red
I like the helmet & sign, it is something that can be recognized easily and used abstract. But... Perhaps it is a bit too simple (not really integrated with the business name)
Since the top5 picking is coming closer and you will most likely be in the top5 with your current entry,
Just a small feedback on your top entry/entries:
+ its simple yet nice + it has alot of potential
working points:
* although it has a lot of potential I still miss that "final touch" * might be more "web 2.0" * the colors are not that good match (if your plan was the belgian flag - it is black yellow red)
Perhaps the belgian flag is not that ideal - a subtle touch to "belgium" is definately a + but the whole name is perhaps too much. check the entry that is currently first for some inspiration...
