AuthenticBlaze asked me how I do those circle backgrounds, so here ya go!

So first I start by just dotting on my canvas (I deselected it so you can see everything better) and expanding it so it's big enough for the size I want.

Then I choose my two gradient colors I want on the sides. (The layer is also alpha locked so nothing goes outside the circle.)

After that, I put the Gaussian Blur at 100%, or to whatever percent it looks best blended into an ombré.

Next I select my Broken Glass brush from a brush pack I imported into procreate (that's the program I use to draw). If you don't have this brush, try to find a brush you can edit to have a lot of jitter and spacing, instead of being a line when you draw with it.

Finally, I just run my brush along the circle until I feel satisfied with how it looks. I really like this Broken Glass brush because it draws at random pressures, so I never need to change its opacity if I want a light or heavy pressure.

And there you have it! Hope this was helpful!
