I'm very, very thorough. I'll pretty much read your fic, and at the same time have a writing pad out, jotting down observations--pretty much anything I find WRONG, or weird, awkward, etc. Be aware that I'm not the type to just pick out nice things unless they are actually passed a mediocre level. In other words, I won't asspat you for just anything you happen to get right. It has to stick out to me for me to mention it.
On that note, you must be aware that I'm then, in fact, not your "nice" reviewer.
I'm willing to argue with you, though. If I point something out that you don't agree with, tell me. We'll discuss it. In other words, I'm willing to work with you if you are with me.
I also would prefer it if you specified how you want to be beta'd. Tell me based on this criteria:
• I just want my grammar/writing mechanics/etc. criticized. Don't worry about characterization and plot, or how in character or how close to canon I am, because I'm confident about my skill in that or don't care.
• I'm confident in my writing; I only want you to critique my plot, characterization, and/or how loyal I'm being to canon or the characters portrayed.*
*Note that I might ignore all this if I think you really need help in your writing. Or if I just find some fault in it that you can improve on.
• Rip me apart.
All of these options are available to you, and I will also correct any spelling/grammar mistakes. Please tell me if you're comfortable with me also omitting sentences, switching stuff around, rewriting sentences for effect or clarity, etc. If you trust in my abilities, cool. If you're a bit wary of letting your writing fall into my hands, we can work something out so you'll be able to tell what exactly I'm messing around with.
Oh, and just in case you've never really been critiqued before... be aware that I ask questions. Questions you're not necessarily supposed to answer. When I ask "Why would he do that when blankity blank just happened?"--I'm not actually curious about the answer. It's just my way of telling you that you either need to think something through more, or I'm telling you from the perspective of an average reader that I'm confused and you need to be more clear/logical/etc.
I say this because from past reviews... I've had the author actually answer these questions. Vehemently. You shouldn't have to answer questions that should be answered within the text. You gotta know that quite honestly, unless it's in a fandom I actually really really like, half the time I won't give a damn what your reasoning is--especially if you're telling outside the story. You should answer my questions WITHIN the text, is the point I'm trying to make.
Anyway. If you really, honestly want to improve on your writing, know all this before knocking at my door.
