If description is so important then how can you be overly descriptive?

If you add too much description in the beginning it will be too much work in the end. You won't be able to figure out how to add more description without making it sound like the beginning. Find a happy medium and work with it. I, personally, like a lot of description in my stories because then it makes me read every sentence and the mental picture stays in my mind but I guess you can't make everyone happy. Good luck :D
