- Incorrect grammar/spelling ::
This could be fixed by using Microsoft Word/OpenOffice/etc.'s spell checker and grammar checker. You should also PM a friend (if they are willing to help you), post on the The Critique Cafe, or even the FanSpam Thread.
- History, personality, or sometimes appearance are cliche (overused, unoriginal, etc.) ::
Avoid: perfect characters (Mary Sue/Gary Stu), love triangles, abuse/neglect/etc. ("sob stories"), etc. Try to think of something original, perhaps make up a whole new world in your head and then place your character in that world. Now, sometimes we do get cliche characters (namely histories) that get accepted. The reason for this is that, although some of the character is unoriginal, the presentation (the way it's written and shown to us) goes beyond the ordinary. If it is written well, then it can still pass, but doesn't have as high as a chance of being original. (Why is this? Originality makes someone closer to their character. If you create a whole world, friends, powers, etc. for your character, then you are more likely to be attatched.)
- Form is too short ::
I think this is self explanatory. If your form doesn't meet the length requirement that is in the first post, it is likely that your character isn't developed enough for our satisfaction. If it's not well developed, we feel that you are more likely to abandon or forget about your character.
- Your form isn't finished ::
The last reason that tends to be a big one. More than likely if your form isn't finished, you won't get the character you want. However, there have been one or two (only one or two) exceptions to this. The reason being is that the WIP form may have mostly been finished already, but had shown a good development in personality and some history. Don't let these few exceptions make you feel like you may get the character if your form is good enough, again, more than likely, it won't.
I do realize this may not be exactly what you're looking for. However, even so, I hope it helps the other people that are wondering what might be wrong with their form. :3 Overall, we're looking for good grammar and spelling along with a unique and developed character. Again, if you do feel you need someone to peer edit and can't find a friend or anyone else, you can post on the FanSpam thread or ask a mini-mod if you can PM them your form.
^ Don't ask me though. I don't mind looking at other things, but I won't critique for SLAP because I would feel like it would be cheating. ^^;
