Are you quite new or have you produced other genres in the past?
For me, more organic based textures and letting tracks breathe for this style helps make it "Chill".
Reverse engineer some of your favourite artists, load it into your DAW and see how many "ear resets" they used and how they keep the track interesting. Don't be afraid to learn from other genres too, Some of my ideas have came from listening to orchestral pieces.
I'm making an electronic music. I've just released a new track called 'I can Take It!'. It's a nice House track. Please listen to it/ put on your playlist, and/or follow my music profile on Spotify if you like it. I'll follow back. Thank you and have a nice Sunday.
