Worked up the Repin a bit more, to try push it further would be mostly an insane amount of very subtle colour and saturation tweaks. I'm still getting the hang of percieving the correct colour, more often than not here each time I selected a colour the colour I was aiming for was more saturated. Ah well, that will come in time I suppose, all a matter of learning.
Here's another sketchy B+W random char from the characterdriven generator, coincidentally, a viking again. The description went filthy, jolly, mentor, viking, and yes, I know horned helmets are wrong, but they are fun to draw!
