I agree with Knoxius. Too much compression, makes the mix feel very claustrophobic.
Combine that with the fact that it sounds like every single synth has some form of reverb or delay and it got really messy really fast.
I voted the song 5/5 to raise the score though because the actual song itself is very promising and the current score does not reflect that.
Work on mixing the different synths together to take up their own space in the mix using an equalizer.
Doing this, as well as toning back the compression, should clean up the muddiness of the the mix and overall make you a better producer.
