Very well done works of art here in your thread! And you do the colour-painting in the computer? Looks like real tempera.
I like the background of your last picture already as it is. It doesn't distract from the impressive face and it gives a feeling of depth. But you should do the arrows of course.
Thank you. Yes I do it on the computer and at the risk of sounding like an idiot I'm going to admit that I don't really know what tempera is; but whatever it is, I'm pretty sure it's exactly what I was going fore.
