I'm trying to make use of every spare moment I have to try and push my artwork just a bit more. So during the end of my lunch-breaks I've dedicated about 30 minutes a day to just trying to work on portraits as rendering faces is something of a weak area.
And because I had some spare screenshots I also made a quick progress GIF in case people would like to see the process.
I'll definitely be doing more, but I may just post a select few on here. You can be sure to see them all as I make them over on my Twitter: HERE
