I know it sounds like that, and I kinda like it...it's actually a riff on the second section from Bach's Toccata and Fugue in Dm, just cut off after the first bar. I then added the three repeating notes afterwards because it sounded cool, then realized why it sounded cool...
I was surprised to hear the similarities to Separate Ways (one of my favorite Journey songs), when I was actually including the Bach reference as a very, very subtle DragonForce reference...the opening acoustic guitar arpeggios in Through the Fire and Flames are also an abbreviated version of Toccata and Fugue.
