Yep, sound similar to "Sky Siege" but there is a difference too. Sky Siege sounded like an actual engament track, this one for me sounds like having more parts, like, you know, "reading for the battle"-"takeoff"-"fight". And if this impression of mine is what you intended, then maybe last part should be more emphasized. You may even think of merging this track and Sky Siege in one 4 or 5 min. cinematic piece.
