It's actually fairly easy, and can be done in a few easy steps.
Step 1: Base coat in Tamiya Black Vinyl Paint
Don't worry, if you don't have access to Tamiya Black, it's fairly pricey pot of paint. I detail below a way around it!
Tamiya do this acrylic shiny glossy stuff which dries shiny. Like below...
Step 2: Drybrush LeadBelcher/ Necron Compound
Don't do it too heavily, you really want the black to stand out.
Step 3: Pick out the talons in thinned out red.
Remember, afterwards, go back over the red with 'Ard Coat. Gives it the shiny gloss finish
Afterwards, I go back over in the Tamiya Black in places where I want the the pitch black to really hide areas. That way it gives the perspective that they are jumping from the darkness!
Also, Nurgle Rot technical paint from GW does a wonderful job for slime! I applied it to the tongue and some joints to mix up the colours a bit!
This is the end result of the Tamiya Black base.
So, what if you don't have access to Tamiya Black, well, instead of using Tamiya Black, the answer is to replace Step 1 with a base coat of normal Black.
Then afterwards, just apply the 'Ard Coat to the whole model!
Here is how it looks,
Be careful though, too much and it won't dry properly leaving you with foggy layers on your models.
There you have it!
Also, obviously, base your model as you wish.
Merry Christmas All!!
I will blog up tomorrow for a Christmas special!
