I like your snare, very clear and punchy but a bit too dominant in the mix making your mix narrower than it is. I think you can use FXs more to provide some depth for the mix. Yeah, man, more reverb and delay. I think you can push the hats up a bit; I think you'll get the swing with them. The hats and snare give the song the swing. We should take advantage of that. As far as balances (freq+volume) are concerned, I like the frequency balance more than volume balance. Sort that out and I think your mix will be awesome. Cheers!
