nice laidback intro
oh here comes the drums!
yeah this is nice
bassline drop!! good work mate like the vibe
maybe not the whistle so much it stands out too much in the mix, but that bassline is great.
nice pads in the background, very summery 
probably too much reverb on that snare in the breakdown. but it ends nicely, some eq on the piano to give it some clarity also. but i like this tune man, good work.
