Hey, I remember you from the Spring Tune Jam! How's it going?
This is some top notch presentation. That youtube video is amazing! The arrangement and instrument choices were perfect, and it all fit the underwater tropical fun vibe so well. Its so cute! I really liked how even the music where the character was in danger you kept the fun vibes but had a little bit of an edge to separate from the more fun/chill music.
One thing I did notice in your compositions, especially in the queen and town theme, was that a lot of the music stays at the same volume throughout. Add some crescendos and decrescendos, strip away and add layers a bit more often, etc. for a little extra spice. (usually consistent volume is a good thing when you have to balance it with sfx, but you don't have to worry about that here so go nuts lol)
Also, love the artwork.
