Whoever lettered this thing put a stupidly gigantic word balloon on top of a character's face, despite the fact that there's a huge open spot just slightly to the left of where it sits now. And considering that the background looks on close examination like it might be a photograph of a hallway that's been run through a few filters, I think it's safe to say that it could've used a little covering up. Instead, the problem was solved with a transparency, which at best makes Mike here look like some kind of cyborg, and at worst makes it look like we're reading his dialogue through a glass of water.
Either way, it's jarring, which is what bad lettering does: It pulls you out of the story and puts an obstacle between the reader and the content, and considering that "Twilight" has a very good chance of being the first comic a lot of people read, that constitutes a pretty huge problem.
