Adventure Awaits: The whistle sound is so fun and definitely fits the Mother inspiration. I imagine this working well in a Yoshi game as it has the cute theme on the surface, but has a surprising amount of sustenance when you dive deeper. The soft guitar backing is also nice and calming.
Looking for a Dream: I felt the Pokemon town theme influence on this track! I don’t have much to say about this one other than I think you are talented at melody writing!
Forest of the Witch: The instruments you used and waltzy style remind me of Banjo-Kazooie music in which the spookiness is conveyed while still keeping the light-hearted atmosphere/feel present. The echoey vocals are also a nice touch to add to the ominous feeling of the dark forest.
Starry Night: I agree, I love the sound of this instrument! This is such a soothing and wonderful way to end your OST. I really enjoyed listening all the way through! Thank you for sharing!
