I didn't get into the Mass Effect games until pretty late; far after ME3 came out. There are a lot of great characters in the series (which I plan to get to eventually) but one of the first ones I wanted to do was Jack.
Jack is bad-ass.
Anyway, for Jack I started with the Jinx Heroclix. She's bald and doing something that looks kind of biotic-y, so a good start. Then I trimmed the skirt and tried to make Jack's pants which...kind of worked.
Then came the tattoos.
I almost gave up trying to do the tattoos, but I persevered.
As a side note, this is not the default outfit for Jack. It's her loyalty outfit. The original outfit is still a bit iffy for me.
(Don't tell Jack I said that.)
