Sweater for a Penguin

"Even penguins need to keep themselves warm sometimes..."

Peso

Started on this one a couple of weeks ago, but it was left unfinished until today. Peso's sweater in this sketch was based off of one from the Abercrombie and Fitch website (Textured Shawl Collar Sweater). The heart, if you look closely, has a little X on there - I think it represents how Peso is not only able to treat various patients of many kinds, but also make them feel better in the process. I was thinking of a song from Twenty One Pilots called "Tear in My Heart" at that time (which you can hear right here).
