As a reader, I never take notice of the word count. It's not how many words are used, but how the words are used. I need the words to supply the images in my head. For example, if the scene is set in a kitchen, I really don't need every appliance described; however, if the scene is set in the woods, I want to know what the character hears, is the area dense with trees, etc. I don't have a preference of chapter lengths, either. As long as the story flows, I'm good.
