This is the eldar viper jetbike.
Like all my eldars I have choosen a blue water pattern for this model.
The bottom parts were primed with white, the top parts with a blue color.
I tried different methods for creating the pattern.
My latest is to use layering with watered down colors.
The best effects can be achieved using an airbrush, but I don't always set it up and I also consider it kind of cheating.
