You are looking beautiful ... today. *facepalm* This is a josei, right? This is written mainly for women. Oh god. I know most of you GUYS around here already know that, but just in case. Never say that to a women! At least put the word "especially" somewhere into that sentence.
A short tale of mine: There were those girls my classmates and I hang around with during breaks back in school. One morning I meet one of them at the school doors waiting to be let in. She looked tired, spritless. I noticed begs under her eyes and I as good as never notice such stuff normally. So I became concerned and ask, "Oh, you aren't looking good today. What happened to you? Are you ill or didn't get much sleep tonight?" That look on her face. Something in between surprised and "I wish my stare could strangle that guy." The breaks in that following week weren't looking so good for me either. Lesson learned.
