The stringed instrument at the beginning is pretty catchy, and the staticky white noise at :07 is cool, even if the attack was a little strong on the latter. At :14, the harmonies work well, but the mix sounds a bit strained. I think there might be a bit too much reverb in the texture, and I’d also suggest looking into adding a compressor on the drums, if that’s an option in Jummbox. The string melodies at :58 are really nice, and the synth riff at 1:12 is really catchy as well. The whole call-and-response structure you have during the middle section of the piece is really fun and engaging. That said, I also enjoyed when you slowed down the pacing at 1:40 and got back to the more melodic content. The arrangement of this piece comes off as a tad disjointed at times, as there are a lot of different sections that play in quick succession. I think the one at 2:25 was a good one to end on, though - it’s energetic and climactic, and complements the outro at 2:39 well. Some of the sound design elements are a bit cheesy, including the sweeps and the (relatively inauthentic) stringed instruments.
I think the biggest problem with the piece is that the texture sounds a bit muddy. An important way I can tell that the mix is not as clean as it could be is that the drums are very hard to hear during the busier sections. There are a lot of ways to go about fixing this, but the most important is probably using what’s called an equalizer, or EQ. You might know this already, but if so I think you need to use them way more often. Basically, every single instrument in your song should use an EQ to filter out all the frequencies below around 200 Hertz, except for the bass and kick drum. You should also try to select and manipulate your instruments so that there aren’t more than 2-3 playing in the same frequency range at a given time, and the visualizer on your EQ is a good way of identifying which instruments are in which frequency ranges. Other mixing techniques you might employ to make the sound quality sharper include panning, compression (especially on the drums), and more advanced techniques like stereo widening.
I’m going over this in detail here because, frankly, I think that this track could be a top-notch piece in this competition if you had paid more attention to the mixing here. Mixing is probably the most technical of the skill sets you need to make electronic music well, but you clearly already have the other ones down. You have a great sense of harmony, rhythm, and progression already. Let me know if you have more questions about mixing. Again, I might not be able to answer Jummbox-specific questions, but you should be able to find YouTube tutorials about how to mix in Jummbox, or more specific things like how to add a compressor to your drums in Jummbox, etc. Best of luck! Keep at it, ButterBees. ^_^
