The attacks on that piano are kind of jarring for me.
Also, synth panned hard left sounds good but I'm not sure why you would pan it so hard.
When we get to our drop, I can tell things were mixed too loudly. You've got some soft clipping going on.
That said, track does sound good regardless. I would recommend you revisit the mix after the competition, strip down, re-do all your volume leveling. That's literally the only thing killing this track, other than some machine gun key attacks.
Protip, make sure your track peaks no higher than -6 dB, then apply mastering FX -- not sure if there even are any on this track, but mastering services almost universally recommend this because it allows you the freedom to shape the end result as you please without clipping. If your mix sounds good here, it will sound good at any volume, and most importantly BETTER when properly mastered.
Definitely recommend looking at mixing and mastering tutorials. You have a good sense for melody and harmony. The mix is your weak spot here. Fix that and this would be a solid 4/5 to 4.5/5 for me, depending on how good the mix is.
