I personally think you should resub.
Before you do that though, you have a lot of restructuring to do. For one thing, re-interpret the melody a bit. Like some of the judges said, the melody in there is pretty much verbatim. I don't think this is really too liberal as much as it's not liberal enough. The original melody is in there fine, it's just too much like the original. Also, make it a bit more prominent.
