From Green Lantern #21 (2007), Part 2 of the Sinestro Corps War, comes this page depicting a moment of personal struggle for Hal Jordan. Prior to this scene, Hal, John Stewart, and Guy Gardner were kidnapped by being sucked into the main power battery on Oa and brought to Qward. On Qward, Hal is then subjected to an illusion of his greatest fear -– the very real probability that his father died in terror:
I like this page because it tells a lot about Hal without him having to say very much. He's on his knees in fear, one hand covering his face while the other hand tenses, showing his internal struggle to not give in to his fear. Then he draws his hand away from his face and, without opening his eyes to look at the figure walking up behind him, indicates that he KNOWS who's there. He doesn't need to open his eyes to know that it's Parallax.
It's not visible in this scan, but drawn in blue pencil over the kneeling figure of Hal is another rendering of him, presumably Ivan Reis's original depiction of the scene. In blue pencil, Hal's head is tilted back and he appears to be screaming. I think Mr. Reis made the right decision in how he ultimately chose to depict the kneeling Hal Jordan. Screaming would have been a bit out of character for Hal in this instance. He's not a character prone to giving in to fear if he can help it.
Here's the finished page:
