Great great drawing! Nothing major jumps out. I will say the value on his left cheek is a bit dark. It's almost as dark as the cast shadows. On the model, it's not quite that dark. Then there's a couple tiny dark shadows on the sideburns by the ear that you didn't get. So, double check your values and then not sure what "style" you go for normally, but you can start doing a lot with edges at the level you're at. Amazing work.

Incredible--amazing work showing all the different planes with hatching!

I think this is a solid, dimensional drawing. I would compress the values on the light side a little, but that's just nit picky, but I would continue the dark background around the whole image. Right now having the black background on one side makes the image look unbalanced. Other than that, quite good :)

I read this article. I think You put a lot of effort to create this article. I appreciate your work.

Well I'm no expert but this is looks so great! I LOVE the the shading, from the shapes to the values. Really like it.

Hello, not a critique, but a couple of questions. 1. Why did you make the background the darkest area? In terms of value range, you kept it pretty close on the face, but then the background is a black. Because of this, the range widens to accommodate the background, and then suddenly it looks like the face is underlit. 2. Why did you put the background on the side of the face? I always thought you added darkness to highlight a bordering bright, or to fade shadows into the background. Instead, I see a clear distinction for the eye socket shadow and BG, and not much stark contrast between light and shadow (only on the forehead and cheek). But yeah, I'm not very good at shading, and was wondering why you made these decisions. I've attached pictures to show what I mean. If you'd like, I have a .psd file with all my edits, so you can mess around with them, thought I think it's too big to be put as an attachment here.
