I'll speak for myself as I can't answer for anybody else.
When it comes to grading.
1. Spelling. Spelling is huge. If you have a couple of words spelled wrong here and there... no big. But if it is littered... yeah I'm going to count heavily against you. Mainly because there are programs out there that do spell check and if you can't do a spell check... yes some characters do use a draw with their talk and that is understandable. But for the most part... watch the spelling.
2. Creativity. Its good to see in ring promos. Good to see out of ring promos. But don't just make every single promo... *person walks down to ring, grabs mic, I'm going to kick your ass and this is why... end promo.* that gets boring. I wanna know what the character is doing. What the character is thinking. How the character behaves. I wanna know who you are and what you are about and if all you do is say... I'm going to kick your ass... then that isn't helping. Wanna get inside your character's head. Let's see their place of dwelling, their past, anything.
3. Grammar/Presentation. Not huge on that but it does count. Like don't have a run on sentence that goes on forever and ever and ever without a punctuation mark anywhere until three lines later. Punctuation helps a lot whether it is to end it with a statement. WITH FORCE! Or to ask a question. But with a lack... everything runs together. And by presentation I mean... don't have some huge block of text that is like 30 freakin lines long and then a new 30 line block of text. That is such a chore to read it will probably be skimmed. And yeah I'm being completely honest with all of you here... if I see a big block of text... I'ma skim it.
4. Fluidity. And that translates into a natural flow of conversation. Don't sound robotic with your talk when you start talking about one thing and then the next paragraph is something completely different. I mean it should sound like a person is actually talking and not robotic. That sorta adds to the realism.
And that's all I can think of off of the top of my head for the moment. But yeah. That's the kind of stuff I look for. Spelling is important because I don't want to sit there trying to decipher what the hell someone is trying to say and can't figure it out becus they tiped lik tis. Creativity keeps things fresh, new, fun for everyone reading, grammar/presentation makes things easy on the eyes for all reading and makes it easy to follow, and fluidity so it sounds and reads natural.
WOO WOO WOO
