Sand texture with a chromatic aberration. Set blending mode to Overlay and set a low opacity (10-25%) for ideal results.
Paste the material
over your drawing, set the blending mode to overlay, lower the opacity to your
liking, depending on the feeling you want to create... and voi-lá!!
Your
drawing now has a nice, grainy detail. ♡
On images with dark (close to black) backgrounds, you can also leave the blending mode as normal, I personally really like the effect it creates! Examples below..
For this first image, the blending mode was set to Overlay, 20%
For this second image, the blending mode was left as Normal, 8%
As you can see, the feeling it creates is different.
And here is the texture itself!

You can try and play around with different blending modes and percentages to create different feelings for your art!! ♡
