I must be missing something because it looks perfectly fine to me

Take stuff out until it looks more spacious. Like the notes on the frig, the dog bowl, the things across the back of the range counter and the things on top of the frig. See if other places can be found for those if it feels better without them. . . . . And normally a frig isn't placed against a wall for door opening clearance for removing drawers inside.

Black knobs and pulls will just add more visual noise. Your kitchen looks fine, though Marta is right: the stuff on top of the fridge needs a home. And if the dog dishes can live somewhere else, you'll feel a little less cramped. Perhaps they'll fit in the corner by the window where they won't block an entry.
