I find, when reading, that long paragraphs of description get me skipping ahead. If it is not vital than the mood is more important and the details can be left up to the imagination. Many people fill in the blanks whether you've left any blanks anyway. You can call someone blond but half the people at the table are picturing the NPC with a different hair colour and if it is not important then let them. My best friend has a mental picture of his oriental character as a big red headed guy. It hasn't affected game play yet.
Same guy, when describing rooms, has a tendancy to do it like this. "The room is rectangular, 20x40, with a large bear skin rug in front of a stone fireplace. In the far corner is a four-poster bed covered with a colourful quilt. A cedar chest is at the foot of the bed. A pair of crossed axes hang on the wall and beneath them is a small table with a rose in a crystal vase." Us: "Let's go look in the chest." Him: "Oh, and there's a rabid owlbear in the middle of the room."
Reminds me of my grandmother, when I was a kid at Sunday dinner. I'd ask what's for dinner and she'd say, "Oh, peas, carrots, potatoes, rolls..." and I'd say "Pork, chicken or beef, Grandma? I don't care about the vegetables."
