I'm afraid your hack didn't really warrant approval- all you seem to have done is change the overworld sprite and edit some maps a little bit. You said your hack's story was unedited (because you can't script just yet), and so it could maybe fit in the Sideshow Showcase- but the maps had a fair few tile errors and stuff, and in general it seems as though this is probably one of your very first hacking projects, public or otherwise- would that be right?
I know it seems really mean, but from what I've seen, people who spend more time checking out tutorials and just practising hacking in the background get on better when they eventually post a thread; that is DEFINITELY true in comparison to people who just post things after about 30 minutes of work. So I recommend taking a bit more time before posting a thread, so you can familiarise yourself a bit more with the basics. :)
