You got pretty close with this one with the pose. But I see why he says "never duplicated". I've had many attempts myself. Awesome background, this photo wins my rare 10/10.
Arm can't be out straight. It need to be slightly arched up in order to expose the biceps. Good attempt and what a great background to do it in.
This is the pose you are trying to duplicate. Now if I can only get myself back to that place when I looked like that.
Yeah ... the "shirtless" gig works,
just like it did for Freddie Mercury.
