I think the flag and background picture layers should go under the actual map layers. Right now you can see the flag through the map; I'd prefer to have the map floating on top of the flag.
The surrounding country's flags look really out of place; I'd remove them or decrease the opacity significantly. The font for the names (Belgique, Deutchland, France) is also very plain and could use a bit of flair. You could consider making it a less bold color, maybe a shade of gray instead of black.
The texture on the map is very visible on the +4 continent, the city, and the two +3's east of it, but not on the northern or southern ones. If there is a texture at all on the map, I think it should be equally visible on all continents. The problem is that the map might look too
plain if you cut that, so maybe consider a different texture or an inner glow on each continent similar to the Portugal map.
The coat of arms looks kind of smooshed right now; maybe you could enlarge it slightly? The title wouldn't suffer from being a few points larger, either.
I think that's everything I see that needs improvement for now. Keep up the great work
