I listened to them. Not sure what kind of comments you're looking for. It's difficult to critique the composition without a score and without knowing the intended purpose/audience.
If you're intending them for concert performance, then I think they're a bit too monotonous. They seem better as ambient music - background music at a boutique or something, although the recording quality could be better, and there are some rhythmic issues that need attention if you're going for a professional release. (Some awkward timing - beats coming early, accel/ritard not quite matching the expectations set up by the harmonic/melodic shapes, etc...) If you're going for film music, then it depends on how well the music captures the characters and the story.
There are some interesting ideas in the pieces, though, and with a little work, you may be able to achieve something that sticks in the memory a bit better. (Like Giacchino's waltz from "Up" or some of Tiersen's work.)
"If we continually try to force a child to do what he is afraid to do, he will become more timid, and will use his brains and energy, not to explore the unknown, but to find ways to avoid the pressures we put on him." (John Holt)
