As I was writing this page, it occurred to me that the comic medium doesn't lend itself well to tension-filled sneaking-type scenes. In a film, you can see the character creeping along, and then feel the suspense as they hide in the shadows as a security guard passes or whatever. And of course it's aided by suspenseful music and editing that helps build and maintain the suspense.
In a book, you can use descriptive prose to build suspense by talking about things like the sneaking character's heart hammering and sweat trickling down his sides as he slowly reaches for a doorknob, so nervous that he's holding his breath in anticipation...
But in a comic, you have to work with still images. You can't control how long the reader will linger on each panel, so that makes it really hard to build suspense for this type of scene. Not that it's impossible to have a suspenseful sneaking scene in a comic, but it's certainly not a strength of the medium.
Anyway, after giving this page a second look, some things jumped out at me that it's lacking, so it'll be getting a minor update sometime in the next couple days.
Couldn't you just use the narrator dude to describe how Eddie's feeling, or perhaps use a thought bubble? As for suspenseful music, the reader could listen to one of the synth music tracks from the unofficial soundtrack or perhaps maybe something like the
Mission Impossible theme song or if the person's feeling kinda silly, then perhaps something like
Rock Lobster.
Another thing, the whole Eddie going into stealth mode and the exclamation point kinda reminds me of
Metal Gear. Who knows, maybe Eddie will end up sneaking around in a cardboard box or there'll be a guard that says, "I feel asleep" or something.
