This theme seems to be challenging. I spent a lot of time looking for and thinking of something salty to draw. I ending up choosing this particular photo which I found here.
I like the fact that the salt is sprayed on a transparent glass where the reflection of the salt and that of the container can been seen. Even its cover was not left behind. Happy to see how it turned out.
This piece was done with AutoDesk sketchbook application and aided with an S-pen. You can see my steps below:
Thank you.
