Focus on portraits for 2019

It has been way too long between posts. I have continued painting and drawing over the last several years but not as consistently as I would like. This year I am hoping to change that and spend more time on my journey to art.
In particular, I want to improve my portrait drawings and paintings.
I've only painted a handful of portraits so I have a lot to learn.
At the bottom is my very first portrait that I painted back in 2010. The photo below is my recent painting of my late father. I would like to revisit at the end of the year and gauge my progress. I wish dad was here to see my progress.
