I have also finished the tartans on all five Champions now - which took quite a bit of time; there really is no short-cut for tartan, it's just accuracy and precision. Overall, I'm quite happy with the results. I didn't want the tartan to be too garishly coloured. I tried my best to keep the colours subtle so that it does not draw the eye too much. I'm set on applying snow to their bases, which will hopefully contrast well with the darker shades of the models.
That's all from me today. Expect an update around this time next week, when I'll be back in Heroes and Legends, working on some commissions. Until then, happy painting!
