Hey, I've just listened to your track!
I really loved your track. I think you used each instrument very well: the drumset beat is great and evolves throughout the track, and the melodies fit very well with the harmonic progressions. Your music fits the theme really well, and so does the evolution. I also really liked the Toby Fox-like orchestration.
However, I think your track could be even better if you connected the sections more smoothly and avoided empty bars. For example, you could let the melody or a bassline play alone for 2 or 4 beats before immediately starting the next section.
Also, to make the track feel more like Toby Fox's music, you could reuse one or two melodic ideas throughout the whole track. For example, if your track has four melodic sections — a calm section, a spooky section, a dynamic section, and a trumpet section — you could structure them around the same two melodies: A, B, A+B, A+B, or A, B, B, A.
Good luck for the rest of the voting period!
