Remembering that my life won't last forever is something that I think about a lot since having my son. For the first time, it has started to feel like I won't have time to finish everything that I would like to. Memento Mori - "remember you must die"- sounds morbid, but I don't see it that way. I see it as a reminder to make the most out of, and do the best you can with, the time you have.
I illustrated the skull based off of the anamorphic skull in the Holbein painting, "The Ambassadors."
