Don't worry about it, lines of sight are hard to get in any art form.
(And considering that the best I can do is stick figures... well, you get the picture)
True, the fact that I take up everything except for, like, the top half-inch of that side would mean that it would be hard to look up enough without making you look funny... not to mention that these sight lines are also 3-d so technically you're staring not just up, but at the wall to my left.
Besides, if it were all 2-d, then that would also mean that Lamp is examining the collar of Tally's shirt----no further comments there.
With my lines it looks like you're glaring at Tally. *points at above post*
...then again, this is going with one eye per person. This is be nit-picking now, but Tally's left eye is aimed higher than her right eye, Nathan's left eye is aimed lower than her right eye (glasses make this one tricky to tell), And Lamp seems to be staring at the photographer with her left eye, and right with her right eye.
