About AR 8.5, it's obviously your own decision as a mapper to set the AR to whatever you like, and most likely no one is going to convince you to change it, but I'd like to say one thing while I'm at it. By setting the AR to what you have right now you basically restrict, and furthermore, discourage most of the players from playing it. The map's main difficulty right now is the note density and there's very few people around that are fond of this type of challenge, perhaps you should think whether sacrificing your map's playability for the sake of 'respecting' lesjuh's mapping style is actually worth it. I'm pretty sure most of the people capable of playing old lesjuh's Dragonforce maps would enjoy his maps better with AR9 or higher. More, maybe I'm assuming things, but I'm pretty sure lesjuh himself would set the AR to a higher one if he was mapping those maps today.
You will obviously do as you please, just dropping by with my two cents.
