Well, it's kind of unfortunate you haven't gotten any feedback here yet. Really, the sound of the song itself is already good. Assuming you can mix well, I don't think you'll have any trouble there.
As for the arrangement, there's plenty of things you can do. You could get into an four-on-the-floor switchup for the second drop. Or you could go for something more chilly. I have seen, on occasion, a future bass tune turn into a melodic DnB song on the next drop. You could turn it in into something "harder", closer to trap. You could omit all other drops entirely. Just remember that it's YOUR song. You can make it as long, short, or as futuristic as you want.
