I really loved all the different musical ideas that you have in here. If I were to recommend one thing its the very copy and paste feel that you create, each time you remove something and bring you could feel the copy and paste. to get around this do thing more to vary those elements each time they come back in (something that isn't changing what instrument is playing the idea, there so much you can do with small musical ideas. Other than that I really love the atmosphere you created with your tracks, Good work :)
