Great! Your OC is only 10% Mary-Sue/Gary-Stew, quite a feat when it comes to writing OC fiction. Your OC is probably an over-all well rounded character, with only a slight sense of idealistic, which in small doses can be a good thing, but we're talking VERY small. Like Edward Elric small. So just stay on track, and you'll be fine! XD
Why not tell me what you got? All you have to do is press that little button, right there. Right down there. You know the one. All input is appreciated! :)
