Loaded up the file and was quite surprised by the contents of that first cave. Bonus points for that.
When you add in the remaining dungeons you'll want to move the warp square to be immediately WITHIN the doorway, though, so that Link enters the door instead of appearing in the middle of the room.
EDIT: Whew, the overworld is quite exhilarating when you don't have any weapons. "WRONG CORNER DUDE". Ouch.
EDIT EDIT: Didn't notice because I usually play mute, but the quest doesn't have any music.
