I think the hair is doable, but you'll have to work for your own muscles. The lace pecs are a dead giveaway.

But seriously, I encourage you and any errant reader to go for the shaggy, head-banging hair. Not only is it unconventional, but it's also much more forgiving in terms of application and coloring mistakes. Before my hair started to thin, I rocked a Beatles moptop for many years - complete with a 70's era McCartney mullet - and it became an important part of my persona. I liked that people could guess without ever having spoken to me who and what I identified with musically. External accessories, like clothing and hair, are important ways we advertise ourselves to the world. Think of your skull as a billboard for rent.
