That one guy really doesn't seem willing to be there... it's strange seeing all the happy people around him, yet he's looking down; containing his emotions; holding his peace, as the title says. I feel like the others should notice. Like his aura of unwillingness should break the spell somehow. He grabs your attention right away, so it's like a loose end in the scene.
But I like how visual that is, and the detail is good, albeit somewhat simple, with expressions not all that detailed. The frame with the hands is the one that really looks perfect. Only bit that feels a bit off is the angle in the final scene, when his head is somewhat too big for the picture. Angled so that the girl could be looking at the other guy though... you wonder what's going on outside the frames of what this picture shows. What expression she holds there. What's in their minds. Really makes you think, this piece.
