Based on Sukunami's AU fic For Nothing, For Everything. And I couldn't be arsed to fact check what her Squall looked like (or if he even had that trademark scar) soooooo yeah.
Though I do remember the staff was dark red with runes on it. Thought it might be sort of neato if the staff was a bit organic looking. *squints* I suppose for design purposes I have this universe pegged as being somewhat medieval, though I'm quite sure I hadn't thought it that far back when I first read it ...
Colored in OC, prettied up in PS
