Even though these models look great (especially the gold details on Grimaldus), there is one thing that might be hurting your score; the red doesn't have much depth in it. You should try washing the red parts with some reddish brown, rehighlighting them with red and then giving them some orange highlights. Some blacklining between the tabard's red and offwhite parts would work wonders too. The skin tones look great, especially on the servitor carrying the eagle statue.
