The fun thing about sketching monsters and aliens is that you can do whatever you want. As you can tell from the picture: these were done in my sketchbook. I tend to sketch using a mechanical pencil. Even when I do life-drawing I like to use my trusty Zebra. They’ve changed the design of the pencil over the years, and I can’t find the same style that I used to use back in high-school. The new ones still have the right shape and they even have better grip/cushion, but there is just something nostalgic about the old ones.
