Awesome job, FTA!! When you did your teaser, it confused me to no end since it was a remix for a song that itself was a teaser. We probably won't have to wait too long for that to be corrected. HFX mentioned on Facebook that she will be posting a complete song sometime today.
As for the piece, you did an excellent job remixing such a short sample. You also did a fairly good job matching the style closely to what you intended (Research Facility/Jabba's Ship). I agree with what ZStriefel said below about the dark, Imperial mood.... excellently done!
The only problem I have with it is starting at 3:27 when the trumpet comes into focus. It starts out ok, but quickly at 3:29 it sounds tinny and flat (like the sound-font it is)... especially so when it starts the 32nd (?) notes at 3:32. It continues like this until the crescendo at 3:40... where it sounds not so much different as appropriate to the call and response section there. I know you were trying to imitate the guitar that comes in on the original piece. Aside from the small section I mentioned, I think you got that imitation pretty correct (especially after re-listening to the original).
Overall, excellently done on such a short sample.... especially so considering the difficulty of doing a remix on a piece that has not yet been released fully to the public. Like you, I await the final product. As ZStriefel mentions below: "It truly is the musician that makes the difference." Keep up the excellent work!
