I am not keen on drybrushing as an all-purpose method for hiliting. It's the Sikhs for me.
Well, aren't we just Mister Fancy Pants?

Actually, this is the third version of the paintjob on the big fella. I tried doing a blend technique on him, but ran into two issues:
1: This bastard is HEAVY. I have severe tendonitis in my right elbow, and manipulating him got very hard to do very quickly.
2: There are too many little bumps and bits to try blend highlights on. My patience ran our very quickly - and I had used a drybrush technique on the warp beasts, so I tried it. I have to say I was satisfied with the results.
And lets face it, those Sikhs are damned fine. Beautiful work on those.
