Thoughts while listening:

Not sure I'm big on the initial faux-bass sound, but it does have a certain ambience. Reminds me of the type of music in the old Sega game, Streets Of Rage 2. Kinda feels a little understated. OK, finally we get a lead line at 2 minutes. Aaaaand it's gone by 2:30.

Thoughts after listening:

Well, you've created the title mood, so that's good. I'm not sold on the composition, if I am to be honest, and here's why;
-In a 3:30 second song, there were 3 minutes of, well, repitition. It sounds like you wrote a loop that you liked, and cut/paste it for several minutes, then tried to add slight changes to make it work for the whole time.
-The lead did not work, melodically. I know that you're going for a tension-building sound, but there's a difference between tension and plain wrong notes. It feels like it wasn't planned out, or practiced. It's far too short, and it doesn't go anywhere. There's no resolution. The song definitely needs a lead, and it needs to be the reason for the tension-build-up you have created in the background.
-The original bassline is cool, but it just goes on too long without alteration. A key change or bridge or chorus/verse structure would help a lot here.

Some good things:

-You have a very good background mood. This project is not wasted effort, and could be developed much further.
-Your mixing is quite well-done. Nothing is overdone or lost in the mix.
-The instrumentation actually works well in the song, despite my initial misgivings. That only shows my own bias towards live instrumentation.

Overall, this song is a decent start, but I don't feel that it is a fully finished project. Spend some more time developing a coherant lead, and perhaps look at your structuring. This song currently has only one section, and it could really use some change-ups to bring the original feeling you're trying to express home. Contrast makes the picture clearer.

Hope this helps. 3/5 R4R
