i would say to vary it a lil during the drop... maybe switch the drums a lil or drop the drum at the end of a 8/16 bar loop.
maybe introduce a new sound...like how youve done for the second drop with the piano
quality sound in production as usual, but the bass was really lacking on my monitors, not strong enough atall... also realy feel the drums just need a bit of splash behind them to keep it rolling, they sound a tiny bit dry! hope that helps!
