I've been drawing these guys for years. I call them gummies; they are little squarish squishy things. They are mostly there to populate the margins of my notebooks or fill in spaces on my sketch pages. I also use them for expression studies. They are so small and have so few lines it's a real excerise in economy of line to see what kinds of expressions I can get from them. Here's a whole page of that (and a smiley demon!). Enjoy!
