Negative Void

I drew a box in 3D and decided to paint something on top of it, I like these kind of little scenes and may do them more often. I also tried to work with 1 brush only, in this case a very flat opaque one. To get variety in my brush direction I basically rotated it in the brush window any time I was painting on a differently orientated surface. I am also painting with opacity pressure on but I think I'll adjust the pressure setting of my tablet as I still have to press to hard to get full opacity strokes. And all the layering of semi transparent strokes results in a more blurry and muddy picture.
