Cool! Kinda liking the beat and it's melody. If I were you I would make a different bassline, the only bass I hear is the kick and in the background there is just a weak wobbly sidechained bass. For the build starting at 0:54 I think you could have used a rise sound. At 1:08 and 2:58 , I prefer an instant start of the 4-on-the-floor kickbeat instead of waiting to kick it in for 1 bar. Also, I really miss the open and closed hihats, especially in this type of music. It would make a huge different and it gives the beat a huge boost. I really like the mixdown. Good use of up and downlifters. There is no such problem about the mastering. Not too loud nor too harsh. I also like the melody change in the end at 3:50! Good work dude!
