Macro Doggy footprint

For my 18th birthday, I was given a macro lens. It is probably the most amazing lens i have ever got, so I decided to do a bit of experimenting. I drove myself down to the sailing school, which takes you along the edge of the river, whilst I was walking down the path, When I saw the dogs footprints, I seized the opportunity and took a really good close up of the print.
