I like your style, but I think some areas could do with some improvement. You should try broadening your spectrum from 3-4 cords strumming in an up-down pattern coupled with filtered vocals. Your songs tend to get sort of boring sort of fast, and I think it's due to the fact that you songs are the same the whole way through. Try switching it up with a chorus with a different strumming pattern and/or chord progression. You may also want to go for a more complex strumming pattern throughout the entirety of the song; when all you hear is up-down-up-down for a minute or two people tend to just zone out. Finally i'd suggest maybe putting a little more thought into your lyrics; while they may seem deep and mysterious to you, all i'm hearing is, "something mysterious, symbolic something or rather. ASK ME WHAT IT MEANS!", it ends up getting kinda weird.
Anyways that's my take on it. Please understand that I'm only writing this help you improve, and I'd like to see what else you can do. As I said before, I like your style, but if you make some adjustments and mix it up a bit your music would improve exponentially.
