I like the rhythmic synth at :01 and the added harmonies at :13. This piece is really catchy, but also a bit minimal. The mixing and mastering is really clean, and I love the descending mallet line at :52 and the bridge with the strings at :57. The pace of the piece is pretty fast - the texture seems to abruptly change every 15-20 seconds, with just a brief riser or drum fill to smooth things over. I think you've gotten really good at production, sound design, and creating dense rhythmic patterns. A good next step for you would be working on the arrangement of the piece - give it a cohesive, overarching "story." Right now, this piece sounds like a string of different ideas playing in succession, with not a lot tying those ideas together. Some more gradual transitions might help in that regard, but a little more repetition of some of the core motifs from the first minute or so could also help. You already do that in a subtle way with the low-register piano line at 1:30, but the instruments you're using have changed so much in the preceding minute or so that the piece still doesn't sound very coherent. Does that make sense?
I'd also encourage you to reach out for feedback to the judges who actually scored your piece in the competition, if you haven't already. Cheers! ^_^
