Nathan, I think the second one is the original.
I base this response on the slightly over defined egg shape that is created in the second image, while I see...less of a flow or rhythm in the first image.
I will go no further until I find that which is which. If I am correct, I'll have more to say. If I'm wrong - I don't want to stick my neck out any further!

(By the way, they are both very close. Anything I say is of the smallest consequence. If you are worrying about the difference being obvious, it is not.)
