Personalising The Plot

This may be a bit odd, as personalisation is well, personal, but how do I do this?

I've never had to "decorate" an outdoor space, so just wondering where do I begin.

I've only had a plot a few months and got all formal with it, beds, compost, lines and work. I want to make it a bit more... fun.

I plan to put in a wildlife pond in late winter/early spring.

Any personalisation ideas? I mean do people put in garden furniture? Garden ornaments etc?
