I used to really dislike Games Workshops' introductory sets as the models they came with typically had very little variation involved. That said, I think Dark Vengeance is great. I'm of course biased as a Dark Angels fan, but its pretty awesome to see models like this guy included as well as the sweet looking Chaos models I can eventually paint.
I really like how this model turned out overall. I think the only thing I'd wish I had done was I tried a bit of dusting lighter blue shades on his right hand to play with the idea of him using some magic effect, but never really went anywhere with it. As a result, it looks like weird highlighting. Oh well! I'll try to tackle light effects another time!
