3D depth perception, relative to other strokes, is limited in VR, so it would be good to have more feedback where strokes will appear.
One way this could happen is to visually provide a 3D indication of the stroke, and when the brush collides with existing strokes, the vibration on the controller could briefly be pulsed to give a sense that you would be drawing in a way that is "on" or aligned with other strokes you see.
