I have been toying with how to paint my Space Wolves and in my searches on Google I stumbled along this tutorial which I had to share with the dakka community. I really like the results that came from this guys painting techniques. I would imagine painting like this would take a long time, maybe longer than I would like, but it has inspired me to try to paint in a more detailed and exact manner. Check it out, I don't think you'll be disappointed.
