I actually think you did a great shot here with the exception of one thing: exposure. Break out the tripod, set a timer (so that you can open the shutter without your hands shaking the camera) and do a longer exposure.

Lots of advice here is assuming you dont want the shadows in their current config (I rather like them). Also, opening your aperture would make your DoF too short imo. With still shots like this, long exposures are easy to pull off.
