Brain in hemi-section

After getting accustomed to working with the pen tool in Adobe Illustrator, I have finished my latest line drawing. I have to admit I needed to rework some of my lines from the beginning, but I am pretty pleased with its finality. I definitely made some improvements from the beginning pencil sketch; I straightened out a lot of the line work and made sure there was more dimension in the piece. I spent a good two hours debating whether or not I wanted to add crosshatching lines, but I ultimately liked the simple line and stippling effect the best. I think I’ll try and work in some crosshatching for my next pen and ink project.
