Man, Loki's a big crybaby, isn't he? That single heart-wrenching tear is always sliding down his cheek in all kinds of situations. Guess he's either just a really sensitive soul or else a master manipulator. Hard to tell sometimes. But whatever. The main thing is that it always works on Thor.
Poor Thor. You can tell he really wants to kiss Loki, bad. And oddly enough, despite Loki's tears, Thor is the one who comes across as vulnerable in this portrayal. His eyes are closed but Loki's are wide open. Thor's lips are parted while Loki's are firmly set. Thor is focused on Loki but his brother seems wrapped up only in his own misery.
And hasn't the artist done an amazing job on the highlighting of Thor's hair, lips and chin? Stunning, really. So beautifully done.
