Asgard was the training ground for a lot of infamous Citadel sculptors- though I dont actually know who sculpted this one. They probably wouldnt be keen to put their hand up either. However I do have the Dwarfs from the series and they are brilliant. My fave has to be the Black Dwarf, as he appeared in an article by Aly Morrison in White Dwarf. I am also keen to grab some of the chaos monsters from that range.
Hope you like him. He go boo.
