from the photos ive seen of the Dragon Con jack, it looks like the complex arm tats are tranfers as there is smudging on the elbow bends. the Torso tats looks free drawn though as they have no smudging . Different inks, different reaction to sweat and oil.
Serious commitment to such a cool character!
though have to say jia's skin coloured bodysuit is made from a fine dance mesh..and it beyond perfect! plus dont have to go through all the problems of smudging, and reapplying!
Either way, its soo cool to see more Mass Effect characters coming out
