I had to re-upload because I wasn't happy with the arrangement. thanks and enjoy!

I like the idea for the song, but its lacking in dynamics. Try mixing with a lower output and make sure your limiter is off on your master channel. Ideally you should have between -8 to -4 db of headroom before you start mastering. And as for the mastering, try to not compress and limit too much, as it will basically remove a lot of your mixing. But this comes with experience. I like like the style and the buildup. Keep on working on your mixing and mastering and this will be very good :)
