But, please don't get me wrong, but I have my problems with it. Maybe it's just me, but I feel the ntroduction might be a little too long, nevertheless, I like the way of it. The part between 00:43 and 01:42 is very good - I extremely liked it! But then the second repeating of the "organ-tremolo" at 01:44-01:46 and all those which are following in the short "pauses" are too much in my ears. I think, it might sound better just to leave it "blank". The tremolo is too much disturbing the rythm and tension of the music. What I like pretty much is the passage to the "new" base music at 02:13-02:19 with the two "spikes" or drops or however it is called at 02:17 and :18. The part until 03:03 gets my blood pumping, it is very dense and scary (I see my men creeping through the woods and searching for the aliens they heard). Don't know, but after this it losses it's tenseness, but not in a burst, but unfortunatly slowly, and stealthy, like a tire looses air. I suspect, it might be the "FM-tuning signal" the ascending and descending bleeping in the background (the one you also used in the introduction).
Please, don't get me wrong, maybe I wasn't able to find the right words sometimes. I don't mean to be disrespectful - I could never do something like this - but I'm merley trying to help out by telling you what doesn't fit for me. Hope it is ok for you the way I do it.
