I thought I was done with this piece, but I got some good feedback from my previous drawings through the art tutorials site in which I’m enrolled. I tried to apply those critiques to finish out this portrait.
I darkened some areas in, like the right lower side of his face (left to the viewer). Looking at a tiny thumbnail of the reference image, the darkness of that area was obvious. My eye didn’t catch that until then.
And I added in a background to make the drawing “pop” off the paper a bit. I should’ve used a “reverse gradient” background where the background goes dark to light opposite to the drawing’s transition from dark to light. However, I really didn’t want to add a dark background to all of that hair. It would’ve been too much work , and I’m not sure it would’ve come out well. Still, I think the added background gives the drawing some depth.
