I need new photoshop brushes!
So I started to experiment with some in Adobe Photoshop. What I like is the raw texture style. It reminds me of real pencils. But I am not completely pleased with the default texture. I guess I will change the brush texture to an own scan to get a finer sketch book style. The best will be to scan a page of one of my sketch books.
Here is the test sketch result of my first brush versions.
