I bought blank glass eyes which had a round impression where the pupils is. So I just mixed some black acrylic color with water and dripped it into the impression. Once tried I painted the rest of the eye.
The fur I'm using is from Mendels in San Francisco, they got a web shop at mendels.com. The fur is called "fox - white".
Once you air brushed the fur you have to brush it thoroughly (I use a dog brush for it). As long as you just brush to top layer of the fur, you are fine. I overdid it on the back fur of my bodysuit and now the fur isen't that soft anymore.
To date, the colors are still the same and I got the mask at my window looking out into the street - so its exposed to sun light. Well, most of my neighbors were a little bit upset to see a "big dog" in my window...
I got the paint at a local shop. Its called Createx Transparent Airbrush Color. The ship assistant recommended it for faux fur, so I bought it took it home and tried it out. Dunno if you can was fur which is air brushed with that color.
The paint I'm using is called "Transparent Createx Airbrush Colors". I just bought them here at a local store in Germany, though they are made in the USA. Basically I just used the colors black and light brown. To get some areas darker, I just painted over them multiple times using a comb to prevent the fur from sticking to each other in between.
This looks super amazing, the airbrushing surly makes it look more complete! May I suggest adding more black around they eyes since the eyelid looks very faint in the second picture, which will intentionally make the blue pop out more.
