I was actually looking forward to today's challenge. Artwork can be a really neat theme, that is, until you struggle to find something you can reinterpret.
I scoured Google hoping for something abstract and splodgy, and found nothing I liked or that I thought was doable.
So in the end, I settled for this - the evolution of an apple! It's supposed to depict the various ways you can draw / paint an apple, from sketching, to cartoon art, pointillism and more "arty" versions.
I kinda like it - at least it's different!
