I'm looking for an awesome chillstep track with memorable melody

The track would have different sections and avoid being repetitive. Should be a fun project! It's for an audio project soundtrack. Please send a demo if you can. It would be very atmospheric with ambient drones playing throughout. They would be really absorbing and powerful. The main melody would be memorable and be easily varied throughout. The drums could change too for some variation. It would be about 3 minutes long. Something you can listen to over and over again. Here's some ideas: https://www.youtube.com/watch?v=llER0HOvN0s https://www.youtube.com/watch?v=q5Vu_Vl70Vs
