Thank you! Though I actually use the most basic brushes photoshop has to offer, that is round brush with lower opacity, or the opacity that changes with pen pressure, and soft round brush. These are the first ones on photoshop brush list which have black circle as an icon, not brush or anything else. And I put on top a texture which might be the effect you were looking for : )
