the idea is very interesting and fitting in my opinion, i like it
tides of time is a good fitting track for the beginning of the story, sounding all nice but there's this sad melody on a piano with kind of dark tone, resembling how she feels empty, ..."with a sense of dread, a sadness"..., and i think the silence at the end is on purpose or something, kind of like everything stopped when Kiki spots her old sketchbooks.
revival of youth starts very interesting, all those notes are like "memories" that are coming back to her, and as they appear more and more, strings and synth in the backing starts getting louder, adding more to the memories, and then she gets into the world of her old sketchbook. really fits the story!
almost enough - a really nice, sad track, i like the ambience feel of it with sound effects, a great mix of orchestra-like instruments and electronic ones, the bassline is very nice as well.
i see it now - i love it, really beautiful, the synths, the orchestra in it, its just great, very pleasant to listen to.
overall, i liked both the story and the sountrack, its such a pleasant project to listen and read to, great job!
