I just finished painting a unit of 20 barbarians that I will use for WHF 3rd edition Norse army or as Chaos thugs as well. These figures were sculpted by Mark Copplestone for Grenadier long ago but they are still a great purchase nowadays.
I primed them with Army Painter Barbarian Flesh primer and then washed them with Army Painter soft and strong tones. The magnetic bases are from Sally 4th.
I also will use some of them as berserkers for my Viking army...
...or as Conans for some CROM games. The one on the left could be a young Conan storming Fort Venarium and the one on the right a more mature Conan after visiting some cities in the South.
I am seriously thinking about buying a cavalry regiment for my Chaos army.
