This started as one doddle of the dude in the far upper left corner, all alone. I had no thoughts or intentions. Then I scribbled the other little dude who for some reason was prompted to ask a question. I recognized I had a misspelling and it evolved from there. I knew I was looking for sullen, and of course I was familiar with solemn, but when I did a google search on "sollum look" both sullen look and solemn look came up. Since the definitions were almost opposite - sad and serious, respectively I figured that was a nice play on words and this is what you get.
