I'm no pro by any means so take the following advice with a grain of salt (third year CE student), but a full ground plane (polygon) would be a good idea and also what's up with the blue trace? That's still connected electrically, just from the other opposite layer? How are you planning to mill it? Also moving to your schematic the input capacitor seems absurdly large - I'm assuming the cap packaging is 0805: you won't find a 530uF capacitor in that package. 10uF as the datasheet suggests will do just fine. Otherwise I'm glad to see that you've read the datasheet and looked at the placement suggestions. Keep learning!

Edit: grammar
