Hey Guys. This is a full graphite portrait. I feel like I managed to get the likeness pretty well in the block in (after several attempts!) but then lost it a bit in the final render. The strange thing was that after doing a much more complete drawing, but before going to full render, I traced the photo and overlayed it on my drawing and everything matched up almost perfectly, so the differences were, at that point, extremely subtle. I unfortunately didn't take a picture of that part. Any thoughts on how and why I went off track would be really appreciated. I was using Tombow Mono 100 Pencils (4H - 2B) on Canson Mi Tientes paper if anyone is interested. This was a birthday present for a friend.

Please give me your advice. I take the photo of my hand and then use the grid system to measure the accurate shape. Critique is appreciated!

Hey David! Amazing work! @Stephen Bauman 's artwork heavily utilize core shadows, I think you should focus on that a bit more. Core shadows are usually the darkest shadows on the form and they are right on the border between the light and shadow. Similarly to the ambient occlusion, no reflected lights travel there.
