Path Textures\Arthas.blp Arthas skin with hammer and book removed, armour redesigned and face/hair/skin tone reworked to resemble Soul Calibur's Nightmare. Made on request.
Nice, why don't you make all the weapons he has, especially the Gally Oar ! LOL! Nice Job, just make it a bit more detail on armor and make hair more blonde, not as yellow like Arthas... 4/5
To mr.szing: They fight the same way because they ARE the same person. Siegfried is Nightmare before he got the Soul Edge. Edit: I know this because i own the first game in the series: Soul Blade.
Anyway, good likeness. I could get you a better shot of his 3rd costume's (what you based this on) armor, as I own the game...
The armor needs more details. I'd try to find a better pic of that guy in the upper right corner and c'n'p his armor onto the skins. I guess that would look pretty good.
