Ok man, I really love the Phoenix Wright series (and its soundtracks too), but this track isn't one of my favourites...
Anyway I think it's an interesting choice.
I think the rearrangement is ok, but you need to improve it for OCR; you can in example try to expand it in a sad, nostalgic way, like adding a piano; or maybe something more aggressive, with a heavy drum...
Don't know what else to say, good luck
