Really like this. Looking at how the track progresses from the drop, you bring in a snare 4 bars in and that's quite early. You might find that bringing in a hi-hat at 8 and then snare with a pad or support riff at 16 is a more progressive way to go. The track seems to miss that high-end percussion that can really add a certain energy. An EQ'd breakbeat loop can do the same kind of thing. I think that will add a depth to the track that it might be missing. Hopefully helpful feedback!

I love the nostalgic touches with the whistle effects!
