I'm not a music guy, so get your salt grains ready. I think these sound pretty good. Nice, quiet background ambience style tunes. The first one is nice, although the exact tone of the piano gave me a different 'feeling' than I would expect in the game. A little more light and airy that I would expect, but not bad altogether The second one is also nice. Defintely more ambiance than music. I was with it all the way till the end, where some of the sounds became a little too rythmic, and began to sound more music than ambiance. I think there is a place for musical ambience and environmental ambience, but I question whether they should be mixed together in the same track. Triggered changes could work with this, of course... music changes are great when done correctly! The third one was probably my favorite, particularly the beginning. Great, dark, brooding musical ambiance. My one complaint is the drastic change between the first half and the second half. This is two different themes smashed into one song, I think, and maybe they should be separated. The first half should continue into a new movement, but it should definately carry over the themes. Also, I noticed quite clearly the chimes used in the first two, sounding like distant clock bells. Nice sound on these. However, in ambiance, I think you may want to avoid features such as these. On a five to ten minute loop, the reoccuring bells could seem strange to a player who recognizes a midnight clock chime occurring every 5 minutes. The chimes would work fantastically as an intro segment that isn't looped, or a triggered musical bit though. Note that this restriction doesn't apply to all features; bangs sudden dischordant sounds, etc. can fit in with the environment and not call attention to themselves. Anyway, just my opinion, as a non-sound designer
