Like BrolfThePaladin said, there are way too many sound effects in this song.
There are also some sounds that really just don't go well together, like 0:42 to 0:48, for example. It just doesn't sound good. Also, this song just sounds like a bunch of songs that don't go well together. You could probably make a few different songs out of this one song.
I won't go too hard on you because this is your first song you've submitted to NG, but it does need a lot of work.
