Here's another update. I changed my technique for the second portrait. I'm now using circulism. I want to try to have a smooth and more natural looking tonal transition. I used 7H, 4H, 3H, and 3B pencils. I'm still working on the forehead, I want to add a little more darker tone. I also started the sideburns.
The paper is not yellow, it's actually white. I forgot to turn on the flash on my camera when I took the photo, the room was dimly lit so the paper captured the yellow hue. I'll take a better photo for my next upload.
