Ramona, I have just listened to aviophobia... it's quite a nice lil tune that, but I just felt in needed more atmosphere... I just think there is a lot of space within it, so you could maybe utilize a few reverbs for the various indivisual tracks. I just re-listened to it and put a reverb over the whole track and it certainly adds to the atmosphere.
I am gonna d/l another one now... I shall let u know what I think if i haven't offended u too much already
btw, if u have no means of putting reverbs to individual audio tracks within a tune get in touch, I'm sure I can help
...also I am curious as to your set up
