O.kaay..
here's a list of things to do in the hades model
1: make sure portrait shows in that ingame portrait box.. for some reason it doesn't
2: give him some death sound before that coffin closes around him. could add some wooden thud for the coffin closing as well
3: give him the usual attachment points, like origin, overhead, chest, hand left, hand right, foot left, foot right, weapon...
4: reduce the filesize by a third if possible
