Hey, this is Ry-Ry! hmm...style.. I am actually a writing tutor and would love to look it over :D
I really try not to be harsh, although when it is really needed i will probably give honest critisim. Depending on how long it is it could take me a day to about a week, I am sort of a procrastinator so fair warning.
I'll often add words or give suggestions on how to make it more descriptive and make it flow better as well as grammar crap:) (i can be a little overbearing and self-righteous so just be prepared)
However, when it is needed: plot issues, and styling issues. And since most of the time I cant really change those things, I probably will give you suggestions on how to make as good as possible. I will also often highlight questionable areas that I think you should maybe take a look at.
Two thing I ask:
1. My "beta-ee" read over there story first. It's okay if you don't, but you would be suprised on how many things you can catch on your own by simply reading it to yourself.
2. Look over it after you get it back. I'm not perfect so just check.
Also as a side note I will probably just give you advice, i will not make major changes. Any changes i do make will be highlighted. so you do not have to take any of my changes/advice if you don't want to.
