For mixing advice I think this track would do well with more variation in dynamic range. Listening and observing the waveform alone it seems like you might have gone with too much compression, there is very little volume differentiation between the introduction and the middle, it just looks like one fat sausage! ease up on the compression this isn't dance music so it doesn't need to be fat throughout. start with a lower volume in the beginning and having a crescendo could do more for this track.
