The big three traits that I look for in a story:
1) Appealing names.
In my opinion, names that are "too pretty" or "too beautiful" are often just as distracting as names that are too old fashioned or whatnot. I'm talking about names like Skye, Tallon, Iylwain, Harrix, Wreith, etc. and all the weird spellings that manage to get created. Speaking only for myself here, these names are just too goofy for my tastes and they distract me from the the story. I'd rather have a nice, easy name like Kyle, Alex, Robert, Jamie, Josh, etc.
2) Contractions.
Some stories have lines like: "I could not imagine pain like that," Jesse said. Abbreviating phrases like can't, couldn't, won't, don't, haven't, didn't, etc. can make a big difference in the believability of the story. If it's in a high-tension moment, then I understand but otherwise, it doesn't hit the eye quite right.
3) Skin quality.
Again, this is just me, but in a story when the narrator specifically tells me that the main love interest has flawless skin or pefect skin, I get a little thrown off. Nice skin can definitely be a big deal with a guy but if I'm going to feel affection and real interest for a character, I need a little hint that the narrator loves him regardless of physical perfection. It's minor but this mention of a specific type of perfection seems a bit materialistic for my tastes. Not mentioning the skin quality is an acceptable omission, IMO.
