Cool man, I'm not a fan of BSG's music in general, but I think your track is an effective complement to the video. My only suggestion would be to maybe add one or two lines of harmony to the long string notes in the beginning portion (the ascending line with the octave doubling), maybe with a bit more of a crescendo at the end. Doing so could really help add punch to the transition when you take all the strings away. Kind of hard to get a feel for how the other tunes will work without video to go with them, but you certainly have some nice material there, especially in the gigapolis track.
