I'm going to edit this post as I listen.

1st song. really good sound FX and vocals and the reverb compliments each other very well the synth at 1:15 could use a more complex note structure to create a hook but doesn't really hinder the overall song.
2nd song: Vocal could use a bit of work. The phaser type effect is a bit distracting and its a bit loud at the beginning but the drums and synth sounds great.
3rd song: great sound could have the bass be a bit louder. Background vocals sound really good.
4th song: Not much to say sound really good all elements complement each other nicely.

Overall great EP I'm exited where you take this
Keep up the good work.
