I've done here a step by step 'How to paint Legion of the Everblight Skin' tutorial.
As is seen in the first two photo's I've assembled the Angelus and undercoated it black.
I continued adding more spacewolves grey to the mix as you can see in the photo below. As well its probably worth noticing that I'm beginning highlight the model by only applying the lighter shades to the higher points i.e. the upper parts of each wing fold and the top of the neck.
And finally I finish off with straight spacewolves grey. Highlighting only the most extreme edges to give the model some really awesome contrast.
If you read this and liked it let me know by leaving a comment. As well if you'd like to see the finished model I'll be posting it up in a couple days.
