I was very unexpectedly engaged with this exercise  and I post my studies below. I did my self portraits in ink and HB pencils. I did 2 in ink, both of them contain images of me and my son. The final results were different: baby appeared better on the one where I appeared less recognisable, so the second photo in a first row below is a collage of best versions of me and my baby.

I also did studies of my own head in a bath towel, which I did with an HB pencil. HB pencil self portraits give very different image even though I did my best. In this particular case I find my ink self portraits as more resembling.

I am also reading a book “Portrait Revolution” which is a collaboration project of several artists, edited by Julia L.Kay.
