I really wish I could like this more... But the smoking thing just kinda kills it for me. It's so OoC for Twilight. Her idea of chilling is almost certainly reading, writing, researching...
But basically smoking as a way to relax doesn't really make sense for her character.
I love the pic aside from that, though. Gives me kind of a "Deserts of Kharak" vibe.
