I definitely agree with MJ that changeups are a must. Seems to me that the main instrument that runs through the whole beat on 4 should be mixed in a little better.
Beat number 3 and 5 definitely needs some changeups in it....sounds good but it's too loopy. Throw some more instruments in there with it and mix it all together. Perfect ingredients for crack.
Gotta be able to throw people off, even if just a little bit to keep them amped up to listen. Also, maybe this might just be my personal opinion, but I feel more attached to my work if I name it. Give it a little bit of creativity. When I numbered them like that, I just feel like they came off of an assembly line with no identity to them, ya feel me?
Fie.
