Hm....
Not too sure if this deserved a low 6, but he is right. It is kind of monotonous. The beat is a little weak as well, and there isn't much for change up. (Which isn't horrible, most of my stuff is ultra repetitive, so no worries there if that's what you like ;) )
I don't know how long you have been doing music either, but this is not horrible, and a noob definitely would not be making music of this quality. (compliment.) I would suggest NOT flooding the song with so many effects, usually I am screaming to crank the effects, but in this case, it kills the drums and background synths. I think you need to do some work on mastering ;)
Good job ^_^!
