Such lovely little pieces. Melodies are a throwback to old Uematsu work (especially the Village Theme). Also, I don't know what virtual instrument you used for the strings on The Child Theme but they come out really well.
As for my personal advice, you really shouldn't be afraid to keep your pieces shorter, they work just as well, and sometime, a cool melody only needs one minute, though I must say you nailed the right balance with that really cute Forest Theme.
