I've been writing long enough that I think I've committed just about every style sin there is. Fortunately I also think I've learned from them.
There are some styles I'm not too shabby at. Noir for instance. For some reason or another I can do that. My old boss bet me I couldn't keep it up for more than a couple scripts. I proved him wrong, I can do it, but it does have my own twist to it. I know I could never imitate the masters of it, no one could ever read my work and think one of them did it. And, for a reader, noir can get old quickly so, for me, it needs to be modified while working on it..
Now, angst. That is a style I can't write in and I refuse to write in. I call it the pseudo-Victorian-lady-in-the-trailing-white-lace-dress-with-ennui-running-her-fingers-over-innocent-white-flowers-that-melt-at-her-touch. It's like people who speak in a hushed half whisper and you want to grab them by the shoulders while you shake them and scream "use your outdoor voice." As interesting as the story might be, it loses me if I feel the characters are all walking around with the backs of their hands attached to their foreheads while they sigh and lament whatever it is they're lamenting.
I don't mind some of that ennui in small doses, say for one character once in a while, but if it's more than a page I start wondering when the last time was that I cleaned the apartment and maybe today would be a good day. (I hate cleaning and anything that makes me want to clean is bad.)
A purple prose style? Oh dear, sorry, by the time you've described how the flowers bend in the wind under the soaring sky and billowing clouds the second time I'm looking for an escape.
My own "style" or so I've been told, is 1. straight forward and 2. terse, but visual. I try to describe things with more of a hint so people "get it" more subliminally. Sometimes I can't, but I try. The "style" I write in is dictated by the story itself so sometimes I get a little more descriptive.
If you've ever read any of the translations of Umberto Eco (The Name of the Rose) I would call his style... verbose. I've tried, I've really really tried but most of the time I think "too many words" and wait for the movie.
I think what @cherrystark says here is probably the most important tip ever. We all read something that we absolutely love and try to emulate but fall short. At least I fall short of it and the simple reason is, that's not "my" style. We've all got our own style and the more we write the more we develop it.
I also think style isn't something to stress over if you're new to the writing game. I would say to be more concerned with the story and the characters and trust them to help you create your own unique style.
