I don't even play World of Warcraft, but this costume, the documentation, and attention to detail is amazing!
I hope I can bring the same amount of creativity, and ingenuity to next build.
I also sympathies with the silicon painting experience. It is difficult to see results since silicon is naturally transparent. So you have to apply it in layers.
The paint thinner dries out very fast, and as a result gunks up airbrushes a lot. So you spend a lot of time just cleaning the airbrush.
In the end the high stretch strength, transparent capabilities, and non allergenic properties are worth it.
