Nice track. I feel that the proximity effect is present. And you may have been too close to the mic. Unless you have a lot of bass in your voice. There isn't a lot of bass in the instrumental so maybe the instruments could come up a couple db to be more balanced with your vocal. Because there is a lot of room your bass/kick does not compete with your vocal so the kick and bass could come up or your vocals could come down, seems there is enough headroom to do so with out clipping. Seems you were very conservative with the overall loudness and this is a good thing but the kick and snare still have room to slap harder...snare is ok, maybe the kick can be fatter just a little.
