Any tips on making a DA CM Punk?

CM Punk's tattoo of the King Cobra logo has "SPITFIRE" written above it.

As for the Straightedge tattoo, I would reccomend avoiding painting the tattoo on both the upper and lower joints -- when it bends, it'll just look dumb, so just paint it on the lower, above his belly button. Take your time, look at a clear ref pic when you're doing it, and be sure the brush doesn't have much paint on it, but is *slightly* wet. Basically, use the same technique as if you were about to drybrush something in, but barely wet the brush. This way, if it's too light, you can apply another thin coat and darken it to make it more realistic without it being too bold.
