Well I've kinda stuck to the GW tutorials so far, but as I'm starting to experiment more, I'm learning the key to smooth blends is using the Lahmian Medium rather than water for diluting the paint.
This makes the layers easier to work, as the more you brush the Liberator Gold the more shiny and Silvery it seems to get as the Pigment is dispersed.
I'm getting faster with it, but at the moment speed isn't my top priority, I'm just enjoying the look of the finished models as they rank up on the painting table
