Eeeeeehm... I'm not in charge at the RP The Uprising, because that is Mira, but I can give some feedback that Mira will most likely give you too:
Please look at the SignUps from other people, what do you see there?
First of all you see they have a lot more content, it is at least 5 times longer than you have.
Second, there aren't as much grammatically errors as in yours.
Thirth, they have an RP sample, that is a sample of how good you can roleplay. Don't you have played any roleplays before? Just make one, we need only to know how good you write/ whta your stile is.
Fourth: Even more content. We don't know what you have in your mind. We need to know who she is, to interact with her. That means: post more personality and background. Are you only brave, or do you have fear against spiders? etc.
Fifth: no one is perfect, so when you have all things from above, check if you have also some negative things about her.
And please look also on AlterEgo's tutorial for making sign-ups:
