He's really hard to draw I think you did well . But maybe next time add more reds greens blues and higher saturated colours for the skin colour - that would add a lot of realism if that's what you want to achieve.
Thank you for the advice! I know what you mean. But the screen shot I was looking off of mostly only had only red in it, from that intense red light on his face in the darkness. I was trying to copy that. But thank you, on my next portrait I'll keep your words in mind. ^^
