In the interlanguage links of the left menu, the "good article" grey star icon is too dark, as a result it stands out too much.
The main problem is that it attracts attention more than the "featured article" yellow star.
As an example, fr.wiki has defined custom icons, which imho fit better (though maybe a bit not visible enough):
.badge-featuredarticle {
list-style-image: url("//upload.wikimedia.org/wikipedia/commons/4/4c/Icone_AdQ.png");
}
.badge-goodarticle {
list-style-image: url("//upload.wikimedia.org/wikipedia/commons/8/86/Icone_BA.png");
}
