My opinion is the same as gavin's except that I have to add another thing. Not only do you need more quality, you also are going to need more than just that one build. You could get accepted for having just one build, but that build would have to be "out of this world" good. Unfortunately, that xbox360 doesn't meet the requirements. That's just my two cents on it, but you can choose whether to regard or disregard it.
P.S. This is completely off topic, but why is everybody using the phrase "two cents"?
