Craig McCracken has had such a huge influence on my style, especially my work post-internship. I find myself doing a lot of; eyes lying flat on the head, and not overlapping. As opposed to say, Spongebob-esque opticals, which, about 4 months ago, I would draw for every character.
Below; Eye's flat on head/body. No overlap.
Above: Eye's have volume. Overlap.
