hi there sir
composition-wise it's ok-ish, melodies have that positive vibe, which I always like, but it would deserve more variations both in instrumental and rhytm aspect, you know a few super energetic bars like in 0:30 and then a few laidback ones, with longer notes lenght, using some other synth sound
maybe try to add some drum fills every few bars, you know a bit juggle with the drum rhytm, four on the floor all the time isnĀ“t much entertaining
mixing isn't super good, I can hear all the instruments when I concentrate, but they are quite drowned by the main lead e.g. 1:59 that arp thing could really add some groove, provided it would be audible! Maybe try to sidechain harder and cut some very high-end on stuff to create more space for hats and so.. and there isn't much of bass, I believe every dance song should be driven by a kick and bass
I would compress the drums more, if you have no idea, try googling drum bus compression, it can really add some punch
hat 0:30/1:15/2:16 is a bit too loud and should have longer reverb decay imo
Overall it has some potential, but there is still a lot to work on
And I think there is no point of leaving newgrounds, I know that it's kinda rare to get constructive feedback here, but you can still get some new fans and stuff here, I guess the more places you post your songs on, the better
cheers!
