Ink Sketches

I am trying to push the subject matter into something more obscure. The large coloured pieces are ok but dont bring anything new, they are just ordinary paintings. Nothing special. But these sketches are something a bit different looking at the painting close up you firstly view the negative space and the squares then the features when you move away. This was painted with ink but I would like to use oils on a large canvas, maybe a series of paintings.

These are the original images below they have been edited to show higher contrast.
