Painting mixed media: Graphite and Oil paint on A4 Paper.

I'm interested in the disappearance. What we leave behind. How our presence on earth fades with time. I also like gender ambiguity in my portraits.
I apply a lot of white oil painting on my drawing covering the details, erasing, blurring. 
The more diffuse it gets, the more presence it gains.

I prefer to work on a simple A4 copy paper. The paper absorbs the paint, it is smooth, perfect for the effects I'm searching.
