I like what you've done with the site. It's clean and easy to follow.
I like that you have a background image, but I'd recommend changing it because you can't tell that it's a tennis court without studying it too much.
Something like this:

on the left or right side might work a little better and the colors complement your logo & color scheme.
Other than that, I really like the site. :cheesy:
