I look to see my words were chosen with care. Bungalow vs. little house, for example. If so, I break up complex explanations with dialogue or interior monologue, or delete narrative black holes and show the technology through an action or summary scene. I look for common words accidentally used more than once in close proximity or unusual words that might be more effective when only used once. Dialogue should speak for itself.

Overuse of anything, except chocolate can be annoying, and even chocolate has limitations. Every noun does not need modification.

I almost always say too much before the story officially begins.
