I asked mom: "Will you sit and pose for me, I need to practice portrait painting. But probably you will not recognize yourself and you will have to sit still for more then 1 hour?" She was very dedicated "painter's mother", so she agreed. I managed to do this sketch in 40 minutes, tried to be quick and not to make her get tired, so missed several very important measurements checkings.. Her interest was huge and she asked me when saw the result: "Is it a woman?")))
I found fountain pen with blue ink on my way to the office. Fell in love from first sight and drew in blue all day long..
