Aha
What is your story about and what fandom is it in? I may be able to give you a review, if I know the series well enough.
Your character sounds quite alright by my standards. Especially if the situation is a bit unusual for the setting, sometimes an OC is necessary to push characters along in the right direction. The way I see it, if the OC isn't hogging the spotlight then it can work really well for the story. Even in well written OC stories, I just tend to end up getting bored if the OC has too major of a role mostly because I want to read about the cannon characters.
As for my story. It's for the 'Sonic the Hedgehog' fandom and it's about....alot of things. It's actually a series of stories.
The first story (the one I'm working on now) is a sort of 'growing into/coming of age' theme. The second's theme is the facing of 'the unkown, fears, and the defeat of great challenges.' The third focuses on 'trust, partnership, and deceit.' Fourth is 'Revelations and acceptance of fate.' I have loose ideas for more stories after that which will eventually connect to the last story (which ironically was the first to be fully plotted) and which focuses on 'accomplishing destinies and the passing of an age.'
There is also, finally, a complete sequal planned after the last story (I keep it separate because the staring character cast will be different from the other stories) which focuses on 'moving on after loss, rebuilding, faith, and burdens of leadership.'
But yeah, as said, I've only got the first four chapters of the first story up so far so there's still a lot that's going to happen. *looks at her notebook full of plot drafts, notes, and research* I'VE BIRTHED A MONSTER!
