The cropping is a little off. If you are doing a centered composition, you need to really center it. The letters running off the right end spoil the effect.
"Take a photograph where complete words -- not just individual letters -- play a creative role in your composition."
I don't see anything creative in this literal, close-up representation of an old pound note. There is nothing of actual artistic merit that the photographer can take credit for. Technically, it is fairly sharp but there is no outside context to create a meaningful experience for the viewer except to show what a 1953 Australian one pound note looks like.
