how to get better? Idk even where to start as this is very raw and underdeveloped, which there's nothing wrong with. that's why we're here to give crit. I just want to let you know it's not easy to give pointers on a 30 second loop.
For what it is, it's neat, I like that you're using the Bassline machine. that's a really versatile toool that can make some cool patterns if you learn to use it fully.
