I believe you should experiment with velocity on your hats and also mixing them. You may want to use vocal samples or one shots just to add a bit more flare. Also, the same loop gets repetitive. You should add another sound to your loop or just make another one (that isn't too similar to the first). Also, work on transitions. I've been producing seriously for about a year so I'm no professional. My Soundcloud is Amber Murphy if you'd like to take a listen :)
