That chandelier seems a bit too small and underwhelming for your room. You'll need a larger one and here is a good way to find the right size for you:

To light a room primarily with a chandelier, take some measurements: get the length and width of the room. Then, convert this number to inches by simply adding them together to find the ideal width of a light fixture. Say that you have a room that is 8 feet by 8 feet. That means 16 inches is the width you should ideally look for in fixtures!

Also keep in mind when picking your ceiling light fixture the bottom of the fixture should be no lower than 7ft from the floor. You have to allow for head clearance if your ceiling height is 8ft.
