I'm not sure what you are trying to do here. If you want me to be able to give you better feedback, I suggest you put in your description what your thought process was, what you were trying to do. That way, in addition to more helpful feedback, I may also be able to provide a more accurate rating, and I'll be able to judge your piece depending on how well your intent came through, rather than by my own taste.
Regarding my own taste, I find the beginning to be very interesting, but once the rest of the song kicks in, I find the limited note variations to be repetitive and, frankly, very annoying. If I knew what you were trying to do, I might be able to put that aside. Right now, though, I can't.
Out of curiosity, why did you name the title "Merus"? I find that to be an interesting title. Also, I don't understand why you chose the thumbnail artwork you did. It's these kinds of things that can help me better know where you are coming from.
Let me stress that I want your piece to succeed. You clearly have sounds and tools to create something great. It's just a shame, I feel, that this falls short of what it could be.
