The steam is the default "cloud" brush in Procreate actually XD it's meant to resemble clouds, but I find it's better for a steamy texture XD it's funny how they make brushes for a use and artists just go "no- you're wrong" XD
I had no idea that it was the cloud brush on Procreate as i never use so it's pretty cool! I also agree I love when an artist takes a brush meant for something like clouds or grass and then proceeds to use it for something else entirely
Heheh- Procreate has a "water" brush that is meant to look like the shadows of waves looking down on water. It's perfect for doing a randomly cracked area of natural stone XD Everything in context XD My colour-fu is weak in comparison to some people though. I'm sure there's a lot of great tricks out there I don't know
