The model is good, the only problem I see is that the white is too....um...white. These skulls have been pawned by the Uruk Hai shaman for ages, they should be either smothered in fresh blood or at least have lots of dry blood/dirt on them. Also, there's too much white on the face, it doesn't look anything like the White hand which the Uruk Hai usually sport, but it could be you were going for a KISS look ;)
so overall, 6 +1 because it's an LOTR model
