Chord progression is nice and smooth. Transition noise is just a little loud.
Nice work with portamento here. I would take down your saws by about 1 to 2 dB, cut off an sidechain the sibilant frequencies more, and take down the reverb sends on everything by a lot. Low cutting them to 250 hz also helps a lot in making room for everything to lay in with the bass. As is, it's really hard to hear the bass and percussion.
Hi-hats and or shakers, I can't tell, are very sibilant and could use much less reverb. They create a high wash that makes the track a bit hard to listen to. Harsh sounding. If you want to keep the same reverb, I'd gate it pretty hard. There's just so much sibilance in this track, it's hard to listen to your drops.
I may have mentioned already, but the accompaniment -- non-melody -- synths are covering up your other elements, especially the bass. It's a tendency I suffer from a lot too in trying to make massive sounds. Try just spacing them out more. It'll help. Your percussion should be the loudest part of your mix -- kick and snare. Those carry you through. Those massive sides, they can be up there, but here they're probably 1 to 2, maybe even 3 dB too loud.
Writing wise, this piece was pretty repetitive, but nothing offensive. I would recommend taking a minute to study transitions -- there's a great video, the rule of pairs, by Kush After Hours, that I think you should watch, and I say this because nothing was inherently wrong with anything you wrote, or boring, but it felt like a lot of the same. I think you may benefit from less is more -- rule of pairs, take away two elements, add or change two elements transitions. Because by the end, even though we had a big wall of sound, I felt like we had been sitting at the height of your piece for basically the whole track after the intro. There were no real peaks and valleys, not a lot of tension. Feel me?
Still good work pulling through to this stage of the competition, and thanks for coming out to NGUAC!
