Wow, this is really cool! I really like your transitions from one part to another and a lot of your riffs and rhythm work sounds especially great.
I agree with Souperion that your brass line around 0:40 sounds a bit muddy. Working with EW myself, I think this a case where you want to use a different sample. Maybe try the Long Marcato or the Accent Legato Slur sample? In comparison, a similar part playing from 7:23 sounds absolutely great!
I also noticed you leave the mid range somewhat empty during most of your remix. For that reason, the part starting around 3:40 feels more balanced to me. I think this is an instrumentation thing, more so than an EQ setting. Is this intentional? It does remind me more of the original game music.
