This game is amazing and I just had to draw something for it. Though I've seen the other amazing contenders, my piece was a learning experience. I mostly tried to focus on lighting.
Anyway, to me Lara looks like she is heard a noise and realizes there is a man entering her camp but feigns that she's looking in the wrong direction to keep him off guard. That's just my interpretation but Lara is a clever bad-ass and that seems like something she'd do.
