My very first piano arrangement

This is my first time arranging a song. Lol, and this is an epic song -- Nero by Two Steps From Hell. It's a tough one to start off actually. But what can I do other than arrange it myself with reference to other score sheets I found? So this is the product of references and experience from Animenzzz's Bios, Guilty Crown. Hope it isn't that bad. I was trying to make it sound epic but failed miserably I think. Well, enjoy...? =/
